Program creation device

A program creation device that creates a control program for a machine tool that performs balance cut in which one tool among a plurality of tools performs cutting and another tool performs cutting while following the one tool and cutting deeper into a rotating work, the program creation device comprising:

• an analysis unit that analyzes a composite fixed cycle in which a predetermined cycle for causing the tool to perform cutting deeper into the work and feeding the tool is repeated multiple times to create a plurality of command blocks for each of the cycles for executing the cycle;
• a distribution unit that distributes the plurality of command blocks created by the analysis unit sequentially as a command program for each of the plurality of tools;
• and
• a command adding unit that adds a first command word indicating a delay amount of delaying a start timing of the cycle of the other tool from a start timing of the cycle of the one tool on the basis of an analysis result obtained by the analysis unit to the command block.
