A numerical controller of the invention includes: an acceleration setting data storage unit for storing acceleration setting data where an acceleration/deceleration setting of an axis of a target machine to be controlled is associated with an application condition including at least a tool number; an execution acceleration/deceleration setting storage unit for storing the acceleration/deceleration setting used when a control of the axis is executed; an acceleration/deceleration control unit for performing an acceleration/deceleration control process on the axis on the basis of the acceleration/deceleration setting set in the execution acceleration/deceleration setting storage unit; and an acceleration/deceleration setting unit for setting the acceleration/deceleration setting of the acceleration setting data where a tool number commanded in a tool selection command of a block read from a machining program satisfies the application condition in the execution acceleration/deceleration setting storage unit.

A control device includes an interface for outputting a command value to a motor driver adapted to drive a motor, a storage portion adapted to store one or more commands for specifying a behavior of the motor driven by the motor driver, and a processing portion including a first arithmetic circuit and a second arithmetic circuit. The first arithmetic circuit is adapted to execute a first process for successively interpreting the one or more commands stored in the storage portion and for successively calculating a parameter set which defines a function relating to calculation of the command value. The second arithmetic circuit is adapted to execute a second process for calculating the command value based on the successively-calculated parameter set, in each predetermined control cycle, independently of the first process.

In a method for operating a machine having a trajectory determined by a parts program and including multiple block transitions with a non-tangential contour, a high trajectory speed and a short operating time are achieved. For a first position-controlled axis, an acceleration duration different from a first period duration can be specified, wherein a transition maximum speed for the first position-controlled axis is determined such that, when the first position-controlled axis moves with the transition maximum speed and the transition maximum acceleration is applied, the speed of the first position-controlled axis has a value of zero at the end of the acceleration duration. The traversing movement is determined such that the speed of the first position-controlled axis, at the transition from a first trajectory section to a second trajectory section, does not exceed the transition maximum speed.

A numerical controller for performing table-format-data-based operation control includes a reading unit that analyzes a command block read from table format data to acquire a reference value and a coordinate value of a control point and outputs the reference value and the coordinate value, a segment distinction unit that divides movement to the control point into acceleration/deceleration segments and a constant speed segment, a feed speed calculation unit that calculates a feed speed in the constant speed segment, and a distribution process unit that calculates the travel of a controlled axis for each control cycle so that acceleration/deceleration is applied in the acceleration/deceleration segments and the feed speed calculated by the feed speed calculation unit is achieved, and delay in the coordinate value with respect to the reference value based on the acceleration/deceleration control is corrected by using the feed speed calculated by the feed speed calculation unit.

In a method for machining workpieces within a machining machine a tool is moved relative to a workpiece (1). The tool or the workpiece (1) travels at a predeterminable travel speed in a travel direction which is predetermined by a movement path (3). The movement path (3) is divided into machining portions (4) and acceleration portions (5). Within the machining portions (4), the workpiece is machined between a starting point (6) and an end point (7) of the machining portion (4) at a predeterminable machining travel speed in a machining travel direction. The travel speed is adjusted along the acceleration portion (5), which is defined by the end point (7) of a first machining portion (11) and the starting point (6) of a second machining portion (12), such that the predetermined machining travel speed is reached at the starting point (6) of the machining portion (4).
