Keys words : Benchmark; LIEBHERR Components Colmar (LIEBHERR COC); INSA Lyon; GMC; MIP2; CETOL 6 Sigma; 3DCS; Tolerance; Tolerance Analysis Software; Geometrical Product Specifications (GPS); Tolerance of form, orientation, location and run-out; ISO 1101:2012.

Objectives:

The design department of LIEBHERR Components Colmar SAS wishes to benchmark 2 Tolerance Analysis Software in a PTC Creo Parametric 2.0 environment: CETOL 6 Sigma V8.4 (Sigmetrix) vs 3DCS V7.3 (Dimensional Control Systems).

The goal of this project is to determine whether one of this tool can fulfill LIEBHERR Components Colmar SAS requirements in supporting designers for tolerance calculation.

Subject:

Data entry:

- 1 or 2 simple case system
(3D CAD Models on Creo Parametric 2.0)

- 1 application case system
(3D CAD Models on Creo Parametric 2.0+2D drawings)

Procedure:

After a period of training in order to get familiar with all software, you will perform the same tolerance analysis in all given systems to compare the behavior of both programs.

You will focus especially on how they manage tolerances of form, orientation, location and run-out as specified in ISO 1101:2012 standard.

Deliverable:

Full report in English demonstrating advantages/disadvantages of each software, in particular in the following domains:

- Management of GPS, Tolerance of form, orientation, location and run-out,

- Integration with Creo Parametric 2.0,

- Results reliability.

- Software usability,

- Computation time.

Supervisory staff:
Patrice CERDA and Eric RUHLMANN (LIEBHERR COC),
Stephane RAYNAUD and Valery WOLFF (INSA- GMC-MIP2).

Way of functionning:
90% INSA, 10% Liebherr COC (work meetings)
