NUMERICAL CONTROL DEVICE, NUMERICAL CONTROL MACHINE SYSTEM, MACHINING SIMULATION DEVICE, AND MACHINING SIMULATION METHOD

摘要

A numerical controller includes one or more of a first reversing point detecting unit that detects a reversing point in an axis direction of a machine based on a machining program, a second reversing point detecting unit that detects a reversing point in the axis direction based on a position command, a third reversing point detecting unit that detects a reversing point in the axis direction based on a positional deviation or position feedback information of a servo control unit that controls a servomotor which drives the axis, and a fourth reversing point detecting unit that detects a reversing point in the axis direction based on positional information of a movable portion of the machine, and a drawing unit that generates an image superimposing a reversing point location detected by the one or more reversing point detecting unit on an image of a workpiece.
