PURPOSE:To enable the cam machining to be performed without causing any necessity for reproducing a machining instruction program when the diameter of a glinding wheel is changed by wearing or the like, by constituting a device so that the cam and the wheel are relatively moved. CONSTITUTION:In the cam machining method, in which a cam and a wheel are relatively moved in accordance with a machining instruction program, given coordinate values (l1, theta1) of a point group on a moving passage in the center of the wheel input from a tape reader 10 or the like, by polar coordinates, the coordinate values (l1, theta1) of the point group given by the polar coordinates in the first converting meana 11 is converted into coordinate values (x1, y1) of right angle crossing coordinate system, and a tool diameter is corrected on the basis of the coordinate values (x1, y1) obtained by the means 11 in a tool diameter correcting means 12 and the correction amount from an repair means 13. In such way, when a diameter of the wheel is changed by wearing or the like, the cam machining can be performed without causing any necessity for reproducing a machining instruction program. |
