Process planning at Sikorsky
Abstract
The software program is called Computer Managed Process Planning, (CMPP). This system employs computer technology to speed and simplify process planning of cylindrical parts. It is aimed at the machining of expensive materials requiring tight tolerances and complex manufacturing processes. Thus far, the program has resulted in a 75 percent reduction in manpower and a 70 percent increase in productivity. The software performs four tasks: (1) it manipulates the manufacturing database, accepting input information from a central CAD system or from an interactive display; (2) it finds the dimensioning reference surfaces, clamping surfaces, and locating surfaces for each machining operation; (3) it analyzes dimensions, tolerances, and stock removals in all cuts for each operation to ensure that bluprint specifications can be achieved; and (4) it prints a summary of operations or a routing sheet.
