The present invention provides a technology for generating an NC program which can secure appropriate machining accuracy. Provided is a conversion computerwhich includes a CPUand generates an NC program for a turning process for a workpiece on a lathe, wherein the CPUis configured to generate an NC program such that displacements caused for a workpiece to be processed on a plurality of machining positions at a time of a turning process are calculated, on the basis of the displacements caused for the workpiece on the plurality of machining positions, a movement path of a tool to be used at the time of the turning process is decided, and the tool is moved through the decided movement path.
