Information processing device and information processing program

An information processing device that generates a Numerical Control (NC) program to be used in a machine tool having a linear axis and a rotation axis, the device comprising:

• a processor including a Numerical Control (NC) program generating unit and a Cutter Location (CL) data acquiring unit;
• and
• a memory storing various programs and data,
• wherein CL data acquiring unit for acquiring CL data including an instructed position of a tool leading end point and an instructed angle of a tool posture;
• and
• the NC program generating unit for calculating a movement position on the linear axis corresponding to the instructed position and a rotational position about the rotation axis corresponding to the instructed angle on a basis of the acquired CL data to generate the NC program,
• wherein the NC program generating unit generates (i) first instructed point data calculated with an initial value of the rotational position and (ii) second instructed point data, which is different from the first instructed point data, calculated with the initial value of the rotational position, and
• the NC program generating unit counts number of inversions of the rotational position for each of the first instructed point data and the second instructed point data and generates the NC program in which the number of inversions is smaller,
• wherein based on the NC program generated by the NC program generating unit, control signals are transmitted by a numerical controller of the machine tool;
• and a machining equipment machines a workpiece in accordance with the control signals transmitted from the numerical controller, thereby suppressing an increase in a machining time and deterioration in a machined surface quality.
