PRODUCTION OF NUMERICAL CONTROL DATA FOR CONTOUR MACHINING

摘要

PURPOSE:To shorten the producing time and to reduce the production cost of the numerical control data by setting the types, the positions and the sizes of plural different basic shapes as parameters for the contour line of a machining shape and at the same time connecting those parameters to each other with use of a symbol designating how to combine the basic shapes so as to automatically generate the numerical control data to a processing machine. CONSTITUTION:The input data are received through an input part 1, and a machining shape defined by the input data is regenerated at a machining shape production part 2. The part 2 regenerates the machining shape defined by the parameter and a symbol of the input data by reference to the basic shape registered into a basic shape register part 5. Then the numerical control data is automatically produced at a numerical control data production part 3 based on the regenerated machining shape. The obtained numerical control data are outputted to the outside through an output part 4.
