PROBLEM TO BE SOLVED: To provide a technique for predicting or detecting an interference between moving members such as a tool and a tool rest by use of three-dimensional model data thereof, in which an interference between a plurality of moving members which independently operate between two synchronization instructions of an NC program can be further surely predicted or detected in advance with a minimum operation time. SOLUTION: The interference between a plurality of moving members including a tool and a work of a machine tool between synchronization instructions of the NC program for individually controlling operations of the plurality of moving members is predicted in advance by generating three-dimensional moving area data of the plurality of moving members based on three-dimensional model data of the plurality of moving members and respective movement instructions given to the plurality of moving members between the synchronization instructions, and detecting the presence/absence of interference between a plurality of generated moving area data.
