Process Capable Tolerancing^TM (PCT)
1 Day

Who should attend:
Designers, Design Engineers and those involved with supplier selection.

The Need:
Just look at any engineering product design drawing revision column and it will become clear that most designs are not right the first time. Inevitably the main problems result from poor tolerance capability. Designers and design engineers need a fast simple way to determine if the tolerances they assign are producible. When picking and working with suppliers there is a need to have a benchmark of process capability to assure the vendor is best in class. This seminar along with the Tolerance Capability Software meets these needs.

Course Description:
The statistical concepts behind the process capability index Cpk and its importance to the engineers and designers will be explained in layman's terms. After presenting an introduction to tolerance stack up using the vector method, the Process Capable Tolerancing^TM (PCT) methodology for creating components and products that are robust to process variation is presented. The Tolerance Capability Expert^TM (TCE) software which facilitates the application of this methodology is demonstrated. The methodology is illustrated through industrial case studies.  

Supplemental Reading Material

Process Selection book provides engineers with the essential technological and economic data to guide the selection of manufacturing processes. The book covers a wide range of important manufacturing processes and will ensure design decisions are made to achieve optimal cost and quality objectives.
