摘要

COFORM (COding FOR Machining) is a code that represents machined surfaces. COFORM may be used as input to computer-aided process planning systems. It describes the parameters necessary to geometrically describe a machine surface. This enables automatic process planning and selection of unit machining operations necessary to produce the described machined surface. COFORM acts as the medium through which data is passed to the Automated Process Planning and Selection (APPAS) program. The APPAS program selects unit machining operations for the described machine surface. COFORM has been designed with a large amount of flexibility,allowing other automated process planning and selection programs to use this simplified data entry procedure as the input medium. Since COFORM describes the specific characteristics (the machined surfaces) of the part,the complexity (and length of description) is greater than any presently available coding scheme. COFORM is designed to supply the necessary information to algorithms that will select the machine tools necessary to manufacture the specified part spectrum,along with the manufacturing processes that will be employed to produce the machined surface. Included in this volume are appendices that present flow charts for COFORM;source listing of COFORM;data file for INIT and the resulting block data subroutine;relaxes input restriction;flow charts for INIT;source listing of INIT;and a glossary of COFORM terminologies.
