【発明の名称】非真円形工作物加工用数値制御装置
Document Type and Number:
Japanese Patent JPH077296
Kind Code:
B2
Abstract:
A numerical control apparatus for machining non-circular workpieces such as a cam and the like is disclosed. In the present invention, roughing profile data and finishing profile data are generated from lift data regulating the shape of non-circular workpiece. The roughing profile data are obtained from roughing lift data. The roughing lift data are generated as changing smoothly such that the deviation from the lift data regulating the finished shape presents within the tolerance of allowance at finishing, and quadratic differential components related to the rotational angle are smaller than the predetermined value. Machinings are performed by the roughing profile data at roughing and by the finishing profile data at finishing. As a result, the high-speed machinings are possible and the machining cycle time can be shortened.
