摘要： A numerical control device reads a machining program and causes a machine tool to operate based on the machining program. The numerical control device includes: an acceleration-deceleration determining unit; and a position-command generating unit. The numerical control device is configured to set the acceleration and the deceleration as acceleration-deceleration data when the acceleration and the deceleration satisfy tolerances decided based on actual mechanical dynamic characteristics, and set the tolerances as acceleration-deceleration data when the acceleration and deceleration do not satisfy the tolerances. The position-command generating unit is configured to generate a position command based on the moving command, the acceleration-deceleration data, and the speed at the end of the command route and the superimposition amount subjected to processing by the acceleration-deceleration determining unit.

摘要： In a transport carriage system, multiple transport carriages travel along a common track and each transport carriage includes a servo system that performs servo control with respect to traveling of the transport carriage, and an intermediate instruction of the servo system is generated in a predetermined cycle by an acceleration/deceleration control unit of a traveling control unit. A smoothed instruction is generated for the predetermined cycle by smoothing the generated intermediate instruction over a plurality of cycles with a smoothing unit of the traveling control unit, and the servo system is controlled based on the smoothed instruction that was generated.
