In a numerical control devicewhich controls positions of respective axes of a machine tool according to a machining program, a commandinstructed to the machining programis analyzed by an analyzing unit, thereby obtaining movement dataand a movement type, an acceleration-deceleration data selection unitselects acceleration-deceleration dataaccording to the movement type, and an interpolation and acceleration-deceleration unitgenerates a position commandby performing an interpolation on a movement route, which is instructed to the movement data, according to a command speed and performing acceleration-deceleration according to the acceleration-deceleration data

Numerical control device

A numerical control device includes: a control unit controlling movement of shafts of a machine tool by a position command according to a machining program and acquiring position information on the shafts; a monitoring point determination unit determining a monitoring point in the machining program and a monitoring shaft according to the type of an instruction or an instruction related to travel described in the machining program; and a monitoring unit monitoring whether error or deviation based on the position information at the monitoring point of the monitoring shaft exceeds a predetermined threshold, wherein the control unit controls movement of the shafts based on the monitoring result of the monitoring unit, and the numerical control device further comprises an analysis unit presenting whether the cause of the error or deviation is a mechanical factor or a control factor based on the monitoring result and outputting the analysis result.

In order to enable tapping to be performed precisely and with an appropriate machining time irrespective of the diameter of a tapping tool, a configuration of the present invention includes: a program analysis unit () that analyzes a loaded machining program and extracts thread-related information in tapping; a gradient determination unit () that determines acceleration regarding movement velocity of the main spindle or the feed shaft on the basis of the thread-related information obtained by the program analysis unit (); and an interpolation and acceleration/deceleration processing unit () that generates a movement command for the main spindle and the feed shaft using the acceleration determined by the gradient determination unit (). In addition, the gradient determination unit () varies the acceleration during acceleration/deceleration of the main spindle or the feed shaft in accordance with the diameter of a tapping tool.

Numerical control device which performs tapping operation by using a main spindle and a feed shaft

The electronic device includes: a display section including a monitor unit having a display panel; a slide unit having a space in which the display section can be accommodated, the slide unit slidably supporting the display section; and a slide piece adjacent to the slide unit in a slide direction of the display section, the slide piece slidably supporting the display section. The display section slides between a retracted position at which the display section is accommodated in the space of the slide unit and an extended position to which the display section is pulled out from the slide unit.
