摘要： When performing the processing while changing the position and the posture of the tool relative to the work, if the speed of the tool tip point relative to the work is regularly controlled while greatly changing the tool posture, the speed of each driving shaft of the machine is increased, whereby the interference may be generated. In order to solve the problem, in the numerical controller which obtains the position of each driving shaft of the machine performing the determination of the feeding speed, the interpolation and the coordinate conversion according to the relative instruction path and the instruction speed of the tool tip point relative to the work instructed to the processing program, when determining the feeding speed, the reference point is provided on the tool or the table, the translation speed of the reference point viewed from the mechanical coordinate system is set to the observation target speed, the reference feeding speed is obtained so that the observation target speed is a predetermined reference speed, and the smaller of the reference feeding speed and the instruction feeding speed is set to the feeding speed.

摘要： Numerical control for machine tools and the like of the genus described in McGee U.S. Pat. No. 3,656,124. Improvements are here described for digital computations and control which cause a tool or cutter to follow successive path segments programmed in workpiece edge coordinates, even though the servos operate to control the motion and positioning of the center of a cutter having a finite and unforeseeable radius. Additionally, automatic smooth transitions from segment to segment of the path are effected with a tangent fillet machined on the workpiece which has a radius equal either to that of the cutter or a value which is designated as a single numerical value in the program command data.

摘要： A multi-system numerical control device which receives input commands for each system and is operative to control the speed and acceleration/deceleration of corresponding moveable objects, such as a motors. Each system has an interpolation unit and an acceleration/deceleration unit that is responsive to a corresponding time constant. A speed override device is operative to generate a speed reduction control signal that is applied to the interpolation unit to reduce the speed and to the acceleration/deceleration unit to reduce the time constant, thereby ensuring that the position relationship between the systems will not be lost even when override is applied.

摘要： Methods and systems for calculating a feedrate for programming a multi-axis machining tool. For at least one control block in a defined machining path: a displacement of a defined machine control point from a previous control block to a current control block is determined; a displacement of a defined feedrate control point from the previous control block to the current control block is determined; a compensation ratio is calculated as a ratio between the displacement of the defined machine control point and the displacement of the defined feedrate control point; and a feedrate for the machine control point is calculated by applying the compensation ratio to a desired feedrate. The calculated federate is used in a control block of a multi-axis machining tool.
