developed a computer aided tolerance control (CATC) system based on the tolerance chart technique.
A good tolerance chart is a manufacturing engineering tool that prevents overlapping of in-process tolerances that are applied during the part planning process.
Tolerance chart preparation time can be dramatically decreased from hours to minutes for semi-complex, linear dimensioned, machined parts.
Information includes specifications accreditation information, sample calibration certificates, a literature library, tolerance charts and information on new products and services.
"For years, when this complexity demanded, even more hours were spent in manually preparing tolerance charts. It was time-consuming...nevertheless we felt it was absolutely necessary to produce a quality product."
Some manufacturers choose to depend on the experience of the people doing the process planning and decide not to prepare tolerance charts at all.
