EC-211 Dimensional Repeatability

A one-day program devoted to identifying and understanding the significant variables in the die casting process that cause dimensional variation between castings. This course demonstrates the use of mathematical cause and effect relationships to predict specific results.

Workshop Summary:

This course, targeted to the product and tool designers; process engineers and technicians; quality control managers, technicians and inspectors; manufacturing supervisors and operators; maintenance and tool room managers; and mechanics and toolmakers, discusses the dimensional variation in general. A brief review of basic statistical concepts is included, including histograms and average and range charts. Also discussed are the four major types of dimensional variation. The process variables that contribute to the major types of dimensional variation are explored and evaluated. Finally, variation due to measurement is discussed. The two components of measurement variation are R&R, repeatability (equipment variation) and reproducibility (operator variation).
