摘要： PROBLEM TO BE SOLVED: To minimize the man-hours required to generate electronic cam data having a desired cycle time from an NC program.
SOLUTION: A machine tool includes: an NC machining time measurement part 33 for measuring a cycle time based on an NC program while the machine tool is operated by the NC program, an electronic cam machining time calculation part 34 for calculating a cycle time based on electronic cam data from the electronic cam data, and a display control part 35 for simultaneously displaying the cycle time based on the NC program and the cycle time based on the electronic cam data on a display part 30. An operator can check the cycle time based on the electronic cam data, which is difficult to predict from the cycle time based on the NC program, without actual operation of the machine tool using the electronic cam data, and can check a time saving effect of the electronic cam at a glance.
