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.
There needs to be a better way, according to Randall Pasko, chief manufacturing engineer at Equitable Engineering (Troy, MI), who is a user of a computer software program that provides a cost-effective and accurate method of reducing the time required to produce tolerance charts.
For years, when this complexity demanded, even more hours were spent in manually preparing tolerance charts.
Some manufacturers choose to depend on the experience of the people doing the process planning and decide not to prepare tolerance charts at all.
The catalog also offers a useful technical data section which includes: fractional and decimal inch & metric equivalents, standards for metric threads, isometric tolerance charts for shafts, holes, millimeter and inches, and material standards by symbol and material.
