PROBLEM TO BE SOLVED: To elongate the service life of a tool by optimizing a control start angle when cutting a side face.SOLUTION: In S1, each position and deflection amount of cutting edges of a tool is measured and input, and a control amount of each blade line at a rotation angle is calculated with the use of a predetermined formula. In S2, the amount of depth of cut (ae) in a radial direction and a tool radius are input. In S3, a preset formula is used for calculating the amount of angle correction θfor correcting a control position. In S4, the amount of angle correction θcalculated in S3 is added to a control position of each cutting edge. In S5, on the basis of a feed shaft command value obtained by correcting a control position, each feed shaft (control unit) is controlled and then processing is executed.SELECTED DRAWING: Figure 2 |
