As you can see from the logo on the right, we have three sections:

1. Linear tolerance analysis as well as tolerance synthesis.

2. The processing of process data to support the tolerance tasks.

3. The area for multidimensional tasks including the dispersion analysis for
    physical targets.

One training day is planned for each area. The aim here  for the participants is to be able to use the ConvolutionBuilder tool confidently and independently after completed this training. This also includes all the necessary theoretical basics, the knowledge of which is required to operate the tool. These include, for example, the various tolerance approaches, the linear and general error propagation law, the general tolerance model for the optimization of individual features as well as working with the universal distribution density trace including DIN ISO 22514.

The target group are developers and designers who, by their work, exert a significant influence at the expense of manufacturing processes. Furthermore, project managers of improvement projects as well as consultants who want to identify potential savings in the course of their work, as well as employees in quality management who would like to get involved at the interfaces between design and production or work preparation.

    - Case Study: Gear Shaft 
6. Tolerance Analyses on rotating parts
    - Case study: Radial offset adjustment in a Gear Box
    - Case study: Runout analysis on a Pinion Bearing
7. Working with tolerance tables
8. Workshop "The Car Jack"

The aim of the webinar format is to give participants an overview of the available program modules. As a rule, it is not possible to work independently and responsibly on tolerance tasks through this webinar. In order to achieve complete and sustainable professional competence, the three-day seminar is recommended.

Part 1 of 5

Presentation of all three parts of the program as an overview based on a consistent task from practice

 Part 2 of 5

Advanced part for linear tolerance studies, including tolerance analysis as well as tolerance synthesis with downstream tolerance optimization based on a practical example.

Part 3 of 5

Evaluation of measured values from production with the help of the universal approach "Density Trace", German "Empirical Density Function", based on practical questions.

Part 4 of 5

Processing of multidimensional tasks also for physical target variables such as press-in forces or torques with Gauss's law of error propagation. The procedure is explained using a task from product development.

Part 5 of 5

Rounding off the topic with the general and relative tolerance model, which was designed at the technical university of Ilmenau. Based of this approach the adaptive and selective assembly strategy, in German short ASM, will be present. This strategy is able to increase the quality of your target value without reducing any single tolerance!

The one-day crash course consists of the webinar parts. For further details about the seminars, such as prices and dates and about using the software, please use the contact form.
