Control device and computer-readable recording medium

A computer-readable recording medium that records a program for operating a computer as a control device for driving a feed axis of an industrial machine based on a control program, wherein

• the computer is operated as:
• an analyzer for analyzing a command in the control program;
• a corner detector for detecting a corner part at which a direction of a move path is discontinuous based on a result of analysis conducted by the analyzer;
• a corner curve processing unit for inserting a curve into the corner part to round it, so as to adjust a speed along the curved move path;
• and
• an each-direction speed analyzer for analyzing changes in a speed of a directional component in each of move paths in front of and behind the corner part while moving on the inserted curve, and
• wherein when a result of an analysis shows that fluctuations in a speed change while moving along the curve are detected, the each-direction speed analyzer issues a command to the corner curve processing unit to change corner curve processing for eliminating the fluctuations in the speed change on the curve.
