More specifically, in step S91, the length of the entire machining length, that is, the length of the nth "I" minute section Δl when the machining section C directly involved in the machining is divided into m minute sections is determined. In other words, in the case of simultaneous control of the Z-axis and C-axis, according to equation (12), the minute section Δ1.. not shown in FIG. 13), the minute section Δl, not shown in FIG.

In the case of simultaneous control of the Z-axis and the Z-axis, the minute interval Δl is determined by equation 04), and further, based on equation (]5),

Input the final machining shape, that is, the starting point of the groove, the machining point, the machining depth, the machining allowance, etc., as machining data from the input operation section along with the machining process and machining mode. !
L can be calculated, and unlike conventional methods, there is no need to instruct the machine with the axis movement coordinate values of each axis during machining as machining data, and the programmer can do all the calculations manually. In addition, the calculation of the axis movement amount can be automatically performed within the machine tool M without requiring any specialized knowledge from the operator, which greatly reduces the amount of command data to be sent to the numerical control device.
