ABSTRACT:
A numerical control apparatus for machining non-circular workpieces such as a cam and the like has been disclosed. The cam and the like are used in changing the operation from rotational to linear motion. In designing the shape of the cam and the like, lift data prescribing the relationship between the rotational and linear motions is used. The lift data is given by the position sequence on the linear motion corresponding to a number of discrete rotational angles. Also, the tolerance of the positions is given from a functional aspect. The lift data is converted into profile data prescribing the shape of the cam and the like after being smoothed within the tolerance by a regression analysis, and machining of the non-circular workpieces is effected according to the profile data.
