Control device and recording medium encoded with program

A recording medium encoded with a program which causes a computes to function as a control device that controls a machine tool so as to cause a table to move during exchange of tools,

• the program causing the computer to function as:
• a movement distance acquisition unit which acquires a movement distance of the table during tool exchange;
• a movement time calculation unit which calculates a fastest movement time from as acquired movement distance, and a speed at which the table is caused to move fastest;
• a tool exchange time calculation unit which calculates a tool exchange time;
• a comparison unit which compares the tool exchange time calculated with the fastest movement time calculated;
• and
• a speed changing unit which changes the movement speed of the table, in a case of the fastest movement time being shorter than the tool exchange time, so that the movement time of the table becomes longer than the fastest movement time.
