摘要： A controller for a machine capable of performing acceleration/deceleration control to which an optimal tangential acceleration within an allowable maximum acceleration for each axis is applied. A first interpolation section receives data obtained by analysis of a program by a command analysis section, an makes interpolating calculation in every first sampling period to output it into an intermediate memory. A tangential acceleration calculating section determines a tangential acceleration based on each segment and the allowable maximum acceleration for each axis to output it into the intermediate memory. A deceleration target velocity calculating section prepares an acceleration/deceleration pattern for a plurality of segments stored in the intermediate memory, to output it to the intermediate memory. An acceleration/deceleration control section performs acceleration/deceleration control based on the data in the intermediate memory so that the tangential velocity at an end point of each segment is not higher than the deceleration target velocity, and calculates velocity for each second sampling period. A second interpolation section defines a smooth curve based on the output from the acceleration/deceleration control section and the data taken out from the intermediate memory, and outputs a point on the smooth curve for each second sampling period.

摘要： An acceleration/deceleration control apparatus for a numerical control apparatus which controls a tool in a vicinity of a stroke end by making maximum use of a stroke. The tool moves along a locus in an in-stroke region surrounded by a stroke end and carries out machining of a workpiece such as cutting and the like. The tool, which is moved by the numerical control apparatus according to a machining program, starts from a start point and moves up to an end point in accordance with preread machining blocks. The tool moves in response to usual feed speed control except that tool feed speed is decelerated in sections of the machining blocks when the tool approaches the stroke end. The tool feed speed is controlled to a minute speed just before the tool reaches the boundary of the stroke end and maintains the minute speed while moving along the stroke end. The tool is then accelerated after moving from the stroke end and returns to usual feed speed control.
