摘要

PROBLEM TO BE SOLVED: To diminish a downtime stemming from warm-up of a machine tool, and improve production efficiency.SOLUTION: A warm-up planning system that plans warm-up of a machine tool includes a warm-up program memory that preserves at least one warm-up program, a processing plan input unit that inputs a processing plan of a workpiece over a predetermined period, a warm-up program selection unit that selects a warm-up program dependent on a situation of the machine tool, a warm-up time determination unit that determines a warm-up time according to a workpiece, and a warm-up planning unit that calculates a beginning time and termination time of warm-up on the basis of the processing plan. The warm-up program selection unit selects the warm-up program dependent on a workpiece from the warm-up program memory.SELECTED DRAWING: Figure 2
