BSTRACT

This is a 15 hp thesis in mechanical engineering performed at the CAD* support department at Rocktec division within Atlas Copco Rock Drills AB, Örebro, during the fall of 2009. The staff at Atlas Copco Rock Drills AB uses a variety of CAD systems for designing electric, hydraulic and pneumatic systems as well as for mechanical design. This thesis will be limited to the two main sys-tems, “Pro/Engineer” for 3D CAD, and “AutoCAD” for 2D CAD. The primary objective is to map and document different user profiles in the CAD systems, and to create a matrix stating the need for skills and knowledge of functionality and work methods for each profile. Also, a tool that evaluates the actual knowledge and skills of the users compared to their user profile will be created, to see what the actual need for training is. The tool can also be used to verify the knowledge and skills of external consults before hiring their services.

During the fall of 2009 interviews with relevant staff at Atlas Copco Rock Drills AB was performed and the notes from those interviews were used to create a skill and knowledge matrix for CAD-user profiles. The matrix was revised continuously in consultation with the interviewees.

And evaluation tool to test the knowledge and skills needed for basic 3D design in “Pro/Engineer” was created and tested, first on students at Örebro University, then on CAD users at Atlas Copco Rock Drills AB.

The matrix is to be a live document primarily used by CAD support in cooperation with the manag-ers of the departments to keep an overview of the need for competence at Atlas Copco Rock Drills AB. This should make it easier to coordinate training and prepare for future needs.

The Evaluation tool is, for now, only to be used by CAD support to test external consultants before hiring, or for the individual user that wishes to do a check of their skills for themselves.

In the future both the matrix and the evaluation tool can be incorporated in Atlas Copcos tence program “kompetensportalen”. The matrix can be used to keep track of the different compe-tences needed in CAD for the individual employee, but also for the managers to get an overview of the entire group. This will make it easier to perform CAD competence gap analysis and to coordi-nate training. “Kompetensportalen” is not yet up and running completely, therefore I will not give any specific suggestions to how the matrix and the evaluations tool should be incorporated.

Sammanfattning

Detta 15 hp examensarbete i maskinteknik har utförts på CAD* supportavdelningen på Rocktec divisionen inom Atlas Copco Rock Drills AB, Örebro, under höstterminen 2009. Personalen på At-las Copco Rock Drills AB använder sig av flera olika CAD system för konstruktion av elektriska, hydrauliska och pneumatiska system så väl som mekanisk konstruktion. Denna uppsats begränsar sig till de två största systemen, ”Pro/Engineer” för 3D CAD, och ”AutoCAD” för 2D CAD. Det främsta målet är att kartlägga och ta fram användarprofiler i CAD systemen, och att skapa en matris med nödvändiga kunskaper om arbetsmetoder och färdigheter i funktionaliteter för varje profil. Ett verktyg för att utvärdera användarnas kunskaper och färdigheter ska skapas, för att kunna se vad de egentliga behoven av utbildning är. Verktyget kan även användas för att bekräfta kunskaper och färdigheter hos externa konsulter innan de anlitas.

Under hösten 2009 genomfördes ett antal intervjuer med relevant personal på Atlas Copco Rock Drills AB, och noteringarna från dessa möten blev grunden till användarprofilmatrisen. Matrisen uppdaterades kontinuerligt i samarbete med den intervjuade personalen.

Ett utvärderingsverktyg för att testa de kunskaper och färdigheter som behövs för grundläggande 3D design i ”Pro/Engineer” skapades och testades, först på studenter på Örebro Universitet, sedan på CAD-användare på Atlas Copco Rock Drills AB.

Matrisen kommer att vara ett levande dokument, som i första hand används av CAD support i sam-arbete med gruppcheferna på de olika avdelningarna för att få en överblick över kompetensbehovet. Detta gör det lättare att samordna utbildningar och förbereda för kommande behov.

Utvärderingsverktyget kommer för tillfället endast att användas av CAD support för att testa externa konsulter, eller för den enskilde användaren som vill kontrollera sina färdigheter för egen del. I framtiden kan både matrisen och verktyget införlivas i Atlas Copcos kompetensprogram, ”kompe-tensportalen”. Matrisen kan användas för att kontrollera de olika kompetenser som behövs i CAD för den individuella användaren, men även för gruppchefen för att få en överblick över hela grup-pens samlade kompetenser och behov. Det kommer att underlätta vid gap analyser i CAD och att samordna utbildningar. ”Kompetensportalen” fungerar ännu inte fullt ut och därför kommer jag inte att ge något specifikt förslag på hur matrisen och verktyget ska införlivas där.

1 Introduction

1.1 Background

Atlas Copco Rock Dills AB (RDE) in Örebro is divided in three divisions; Rocktec (RTE), Surface Drilling Equipment (SDE) and Underground Rock Excavation (URE). The three divisions are part of the Construction and Mining Technique (CMT) business area within the Atlas Copco Group. The Rocktec division develops and manufactures rock drills, components and automation systems exclusively for the URE and SDE divisions. At its modern laboratory and research centre in Örebro, Sweden, services are provided to all divisions within the Construction and Mining Technique busi-ness area.

Surface Drilling Equipment develops, manufactures, and markets worldwide rock drilling equip-ment for various applications in civil engineering, quarries and open pit mines.

Underground Rock Excavation develops, manufactures and markets worldwide a wide range of tun-nelling and mining equipment for various underground applications.

RDE uses a variety of CAD systems for designing electric, hydraulic and pneumatic systems as well as for mechanical design. RTE has a CAD support department that work solely with everything concerning CAD for all three divisions and sites in Örebro. They are responsible for creating and maintaining the installations and configurations of the systems, development of best practices and work methods as well as providing user support and internal training.

The two main CAD systems are Pro/Engineer (Pro/E), for 3D design, and AutoCAD, for 2D design and schematics. The systems are used for a wide variety of purposes, and the user knowledge and skills varies.

1.2 Purpose

The purpose of this thesis is to map and document different user profiles in the CAD systems, and to create a matrix stating the need for skills and knowledge of functionality and work methods for each profile.

A tool that evaluates the actual knowledge and skills of the users compared to their user profile will be created, to see what the actual need for training is. The tool can also be used to verify the knowl-edge and skills of external consults before hiring their services.

Depending on the time left, the thesis will also include information about recommended training for each profile, and weather the training needs to be specific for RDE, or can be purchased from exter-nal suppliers.

(8)

1.3 Objectives

The objectives for this thesis are:

To create a matrix stating the need for functionality skills and method knowledge for each user pro-file.

To develop a tool that evaluates what the actual need for training for each user is. To perform an evaluation test on a limited group of users.

1.4 Delimitations

The thesis will only include users at Atlas Copco RDE in Örebro.

Only the two main CAD systems, Pro/E and AutoCAD, will be analysed in this project. The evaluation tool will be developed primarily for one profile using Pro/E.

The number of users testing the evaluation tool will be limited depending on the time left when the project reaches that point.

The depth of documentation of the training recommendations will be determined depending on time left after the matrix is completed.

(9)

2 Work method

This thesis is made at the department for CAD support at Rocktec. It will investigate the skills and knowledge needed by different users of AutoCAD and Pro/E and from that information create user profiles. A matrix where the skills and knowledge needed for each profile will be created, to get an overview of the needs for skills and knowledge and use of CAD programs at RDE.

Also, a test of one of the profiles will be created, as a tool to verify that the users have the necessary skills and knowledge to perform their jobs as stated by their profile.

2.1 User Profile Matrix

In the fall of 2009, interviews with the following were performed: URE

Alex Liebert, Group Manager Industrial Design R&D Automation:

Jan Knutsson, Group Manager Hardware Development

The interviewees were selected by Anna Sundberg, manager of the CAD support department. The main issues discussed were the following:

- What different “types” of engineers do You have at Your department, e.g. mechanical, hy-draulics etc.? This to try to establish different user profiles.

- What does an engineer at Your department do in CAD today? This to determine the skills and knowledge needed.

- What would they need to be able to do to streamline the concept to product process? This to investigate present needs not quite met and/or future needs.

The notes from the interviews were used to create a user profile matrix. In the matrix the columns are the user profiles and the rows are modules that contain specified skills and knowledge. The module specifications can be found in appendix B.

(11)

Figure 1: Matrix example How to read the matrix:

MUST: The modules marked with red are imperative; every engineer with this profile must possess these skills and/or knowledge to be able to do their jobs.

NEED: The modules marked with yellow are necessary within the group, i.e. some, but not all, gineers in the group must master the skills and knowledge in that module. Alternatively, all the en-gineers in the group must have a general understanding of the module.

NICE: The modules marked with green are things that would facilitate the work process in that de-partment, but are not in use today.

They grey modules are modules that are needed but does not yet exist.

The question marks are to indicate that the need for that module is not quite clear. Since the matrix is to be a live document, this will be corrected continuously.

(12)

Figure 2: Module specification example

The matrix was sent to all the participants for revision, and after considering their feedback and dis-cussing with Anna Sundberg, manager of the CAD support department, a new, revised matrix “pro-posed matrix”, appendix A, was created. This matrix is to be read the same way as the “current ma-trix”. The new column, “Profile Add on”, was added to make it easier to see the needs for an engi-neer that has extra responsibility in addition to the basic profile.

This matrix is a mix of the skills and knowledge used today, and the skills and knowledge needed according to CAD support and the interviewees.

(13)

Also, an attempt to create more comprehensive profiles was made, without success. They were all variations of this:

Example: URE cabin designer

Figure 3: Profile example

The main profile is ”mechanical”, containing all the modules under the respective headline. There are three sub profiles “construction”, “cabin” and “AutoCAD” containing the modules under the respective name. The reason this idea was discarded was because most engineers, CAD support excluded, will be none the wiser looking at the main profile with sub profiles, but are going to want to see all the modules to get a grasp of the requirements for their particular profile. So this way of organising the modules will only lead to an extra step with no actual benefits.

2.2 Evaluation tool

Once the matrix was created and the modules were specified, an evaluation tool was developed. Because the matrix is arranged the way it is, I decided in consultation with Anna Sundberg, that the evaluation should be of a specific module, instead of a profile. We chose the module “Pro/E Basic” (Figure 4), since my own skills and knowledge of Pro/E is limited, and because it is one of the most frequent modules, covering most profiles.

(14)

Figure 4: Module Pro/E Basic

As a base for the tool I used the educational material that RDE employees get when they complete an external five day course in basic design in Pro/E WF4 ¹. From that I tried to include tests of all the parts of the educational material.

I constructed a rudimentary test, appendix C, which included most of the parts of the educational material. On the 18th of December 2009 students at Örebro University that had completed the uni-versity course “solid modelling” recently, were invited to take the test. Only two students did. Even so, it became apparent that the test was too complicated and took to long to complete. I altered the test in such a manner that everything was prepared, so that the user only has to do specific tasks, and clarified the instructions to the tool. The revised tool is found in appendix D.

A test of that tool, this time on RDE employees, was performed on the 14th of January 2010. There were seven subjects, all with different experience of using Pro/E. The more experienced users com-pleted the test in about an hour, the others in about two hours. After completing the test the subjects were asked their opinion of the test and any suggestions of improvements they might have. From those comments, the following changes were made:

- Further clarifications in the instructions.

- A built in fault in one of the tasks, so that the user must exit from resolve mode, was added. - A task where the user has to deal with layers was added.

- Some of the questions were altered to concern parent/child relationship rather than blend tool. - The name of an unfortunately named part was changed.

This resulted in the finished test, appendix E.

2.3 Recommended training

Due to limited time I decided, in consultation with Anna Sundberg, that I should not look into the recommended training in favour of developing, testing and tweaking the evaluation tool.

(15)

3 Results and Discussions

3.1 Discussion

So, what do we do with the matrix and the evaluation tool?

The matrix is to be a live document primarily used by CAD support in cooperation with the manag-ers of the departments to keep an overview of the need for competence at RDE. This should make it easier to coordinate training and prepare for future needs.

The Evaluation tool is, for now, only to be used by CAD support to test external consultants before hiring, or for the individual user that wishes to do a check of their skills for themselves.

In the future however, “kompetensportalen” is a near perfect solution for use of both the matrix and the evaluation tool. A meeting was held with Magnus Johansson, Competence Development and Employer Branding, to explore the possibilities.

“Kompetensportalen” (=the competence portal) is a competence tool for the Atlas Copco employ-ees. In “kompetensportalen” the employees register their CVs and all their completed trainings, courses and other activities. They can find and sign up for various internal and external training and courses and it is used to book and record appraisals. In the future it is also going to be used as a tool to perform competence gap analysis.

“Kompetensportalen” is not yet up and running completely, so therefore I cannot give an exact proposition of how the matrix and the evaluation tool can be used.

(16)

For the employee:

In their personal space they can see their user profile, possible “add on”s and possible extra modules they have confirmed knowledge of (Figure 5).

Figure 5: Profile

If they click on the user profile they can see all the modules included in their profile, with some kind of indication to weather they have confirmed knowledge/skills of that module or not (Figure 6).

(17)

If they click on the module they get the full description of the module and a link to do an evaluation test of that module, alternatively the date they passed the evaluation test (Figure 7).

Figure 7: Full description

Also, there is a link to the relevant training and/or existing work methods for the module. If they click on the link to the evaluation test, they get instructions on how to perform the test, and on com-pletion a notice will be sent to CAD support.

(18)

For the manager of the department:

In their space they can see an overview of their staffs’ profiles (Figure 8). They can also see how many modules are verified. With this information it is easy to perform a CAD competence gap analysis for the entire department. Just like for the employee clicking on a module will display a description of the module as well as links to training and work methods.

Figure 8: Example matrix for the manager of the department For CAD support:

The CAD support department will have control of the original matrix, continuously updating it in consultation with the managers of the departments concerned. They also have a matrix similar to Figure 8, but showing the status of all the engineers at all the departments. Here they can easily see and evaluate the need for training. They will also manage the evaluation tools and verifications here.

(19)

3.2 Conclusion

To begin with the matrix will be used by CAD support to keep an overview of the need for CAD competence at Atlas Copco RDE. The matrix is to be a live document that will help CAD support to coordinate training and prepare for future needs.

The evaluation tool can be used to test external consultants and for self testing for those engineers that wish to confirm their knowledge of and skills in Pro/E.

In the future I sincerely hope that the matrix and the evaluation tool can be incorporated in “Kompe-tensportalen” in a similar fashion to my suggestion. Although I realise that it will be a time consum-ing project, I also hope that evaluation tools for all the modules will be created. This to maximise the use of the matrix in “Kompetensportalen”.

3.3 Further comments and suggestions

During almost all the interviews the interviewees expressed the need for a more homogenous way to work in 3D CAD. Today the different departments and even individual engineers have different work routines. This leads to problems, both with stability in models and assemblies as well as with the handling of models the engineer is not familiar with, costing RDE many man-hours. The inter-viewees asked for more work methods and/or best practices regarding almost every aspect of 3D modelling.

There are already some work methods issued by CAD support, but they are not always imple-mented.

I have a strong feeling that there are quite a few man-hours every week lost due to this problem. I believe that RDE could save a considerable amount of time and money by investigating this further. I think that this is a good subject to investigate in a thesis, preferably a 30 hp thesis in mechanical engineering or quality.

HOW

To perform the evaluation test, check out the folder “PRO_E_BASIC” from CAD support in IntraLink and set as Your working directory. Then follow the instructions. Save your files so that they can be reviewed by CAD-support.

Note that this is not a test that evaluates Your ingenuity as an engineer, but a test to see how familiar You are with Pro/E tools. Therefore it is not important if minor things do not look like the original, try not to get stuck with details.

The test consists of three parts; basic modelling, basic assembly and detailing. Some parts You will create from scratch, and some are prepared for You to finish. Therefore it is very important that You follow the instructions, otherwise unnecessary problems will arise. Note that the drawings used are not detailed according to standard, but only to serve as support for completing the test.

The test should take one to two hours to complete, depending on Your experience.

If You get completely stuck, skip that task and move on to the next. You may not use the help function in Pro/E.

TEST OBJECTIVE

Complete the watch by altering and completing existing parts, create missing parts and assemble them. Create a detailed drawing of a specific part and an assembly drawing to show the completed watch.

Good luck! Maria Åberg Örebro University December 2009

(26)

Also create a relation so that the shallow shape around the right button hole changes with the size of the hole with a ratio of 20% (i.e the shape should always be 20% larger than the hole). Set the parameters according to “wrist_watch.pdf”. Save.

1:2 Open the part W_BOTTOM_PLATE_EVAL.prt.

Complete the plate according to the drawing “bottom_plate.pdf” with the parameters as in “wrist_watch.pdf”. Save.

TASK 2

Complete the straps and create the screw.

2:1 Open “EVAL_STRAP_1.prt”. Use the pre-existing sketch to create the strap according to the drawing “strap_1.pdf”. Use the pattern tool to create the holes.

Set the parameters according to “wrist_watch.pdf”. Save.

2:2 Open “EVAL_STRAP_2.prt” and complete it according to the drawings “strap_2_A.pdf” and “strap_2_B.pdf”. Use the datum plane “START” as Your starting point to create the attachment. Start with the widest section. When creating the holes, it doesn’t matter how deep the ø2 cut is, as long as the head of the screw will not show over the edge and it looks similar to the original, approximately 3mm deep.

Set the parameters according to “wrist_watch.pdf”: Save.

HINT: Having problems setting the right dimensions for the cut for the flange? Check out how the flange is created in “EVAL_WATCH_HOUSING.prt” and use the same method for the cut.

Also, be careful in witch order You create the features. If it is hard to see how the strap should look, use the XXXXX.exe file to look at the model in 3D.

2:3 Create a part EVAL_SCREW_YOURNAME.prt. Create the screw according to the drawing “screw_.pdf” by using the revolve tool, disregard the threads.

Set the parameters according to “wrist_watch.pdf”. Save.

TASK 3

(27)

NOTE:

When creating the assembly You may notice that strap_2 do not fit the housing perfectly. This is easily corrected, but if You are pressed for time, leave it. It is not important for the

evaluation.

TASK 4

Create detailed drawings. They do not have to match the original exactly, do not get stuck with details.

NOTE: The drawings are not detailed according to standard, only to serve as support for completing this test.

4.1 Create a drawing WATCH_HOUSING.drw. Choose XXXX template . Complete the drawing to look like the original drawing “watch housing”. Create and save a slanted view to be used as 3D view in the right corner (does not have to look like the original).

(29)

HOW

To perform the evaluation test, copy the folder “XXXXXX” to a suitable location and set as Your working directory. Then follow the instructions. Save your files so that they can be reviewed by CAD-support.

The test consists of three parts, basic modelling, basic assembly and detailing. Some parts You will create from scratch, and some are prepared for You to finish. Therefore it is very important that You follow the instructions, otherwise unnecessary problems will arise.

Save.

4.2 Open WRIST_WATCH_ASSEMBLY.asm. Create an exploded assembly drawing with BOM-list. Use the pre-selected template drawing and then go to File Page Setup Format Browse, select “wf_a3_asm”. Use the default exploded state; there is no need to adjust it, even if it rarely looks good. Create BOM-balloons.

Save.

TASK 5

(32)

A) One section that is extended along one trajectory.

B) One section and two or more trajectories that controls the path and the shape and size of the section.

C) Two or more sections merged with a user defined distance, no trajectory. 2.

BLEND TOOL

2:1 What effect does unequal number of vertices in the different sections have on a parallel blend feature?

a) None

b) You cannot create a blend with unequal number of vertices. c) You can only create surfaces, not solid protrusions.

2:2 How can You solve the problem of unequal number of vertices in the sections? a) I don’t have to, Pro/E automatically creates additional vertices.

b) By adding a blend vertex from the sketch feature tools menu. c) By adding vertices using the sketcher tool “divide”.

d) Both b and c.

2:3 How does the Start Point and Direction Arrow effect the shape of the blend?

a) The start point decides which vertex is first, the Direction Arrow in which direction the following sections will be numbered, in each section. Vertex 1 in all the sections will be connected to each other, same with vertex 2 and so on.

b) The Start Point decides which section is first, the Direction Arrow in which direction the blend will be created. The section with the Start Point will be the first and

dominant section, the other sections following in the direction of the Direction Arrow. 3.

RELATIONS

When You regenerate a part with relations, in which order are the relations executed? a) From the top of the relations window to the bottom.

b) Form the bottom of the relations window to the top. c) That depends on how You write the code.

(34)

HOW

To perform the evaluation test, check out the folder “PRO_E_BASIC” from CAD support in IntraLink and set as Your working directory. Then follow the instructions. Save your files so that they can be reviewed by CAD-support.

The test consists of three parts; basic modelling, basic assembly and detailing. Some parts You will create from scratch, and some are prepared for You to finish. Therefore it is very important that You follow the instructions, otherwise unnecessary problems will arise. Note that the drawings used are not detailed according to standard, but only to serve as support for completing the test.

The test should take one to two hours to complete, depending on Your experience.

If You get completely stuck, skip that task and move on to the next. You may use the help function in Pro/E, if You wish.

TASK 1

Complete the watch housing and the bottom plate 1:1 Open the part BASIC_HOUSING.prt.

Complete the housing so that it matches the drawing “basic_housing.pdf”.

Place the M1 holes symmetrically, use mirror tool to place them. The depth of the holes is not important, set it reasonably.

Create a relation so that the shallow shape around the left button hole changes with the size of the hole with a ratio of 20% (i.e. the shape should always be 20% larger than the hole). Save.

1:2 Open the part BASIC_BOTTOM_PLATE.prt.

Complete the plate according to the drawing “basic_bottom_plate.pdf. Save.

TASK 2

Complete the strap and create the screw.

2:1 Open “BASIC_STRAP_1.prt”. There is a pre-existing sketch for You to use, “TRAJ_A”, but first You have to make it visible to be able to use it. Use the sketch and sweep tool to create the strap according to the drawing

“basic _strap_1.pdf”.The pre-existing trajectory should be placed in the centre of the section. Use the pattern tool to create the holes. Save.

2:2 Create a part SCREW.prt. Create the screw according to the drawing “basic_screw.pdf” by using the revolve tool, disregard the threads. Create the chamfer using the chamfer tool, not in sketcher.
