Plastics Workshops and Seminars
Process Capable Tolerancing
Hands-On Workshop
Fee: $700
Instructor: Don Day
WHO SHOULD ATTEND:
Designers, design engineers, manufacturing engineers and supplier quality personnel.
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.
EDUCATIONAL GOALS:
This one-day seminar is designed to explain the statistical concepts behind the process capability index Cpk and its importance to the engineers and designers in layman's terms. After presenting an introduction to tolerance stack up using the vector method, the Process Capable TolerancingTM (PCT) methodology for creating components and products that are robust to process variation will be presented. The Tolerance Capability Expert (TCE) software which facilitates the application of this methodology will be demonstrated. The methodology will be illustrated through industrial case studies.
