Abstract
Official abstract text for this publication.
A numerical controller carries out acceleration/deceleration control over an interpolation pulse produced based on command blocks. This numerical controller exercises acceleration/deceleration control processing over the interpolation pulse based on an acceleration/deceleration setting which corresponds to the command blocks, and outputs a first speed pulse. The numerical controller exercises acceleration/deceleration control processing over the first speed pulse such that command blocks overlap each other, based on an overlapping shared acceleration/deceleration setting which does not depended on the command blocks, and outputs a second speed pulse.
First claim
Opening claim text (preview).
1 . A numerical controller for carrying out acceleration/deceleration control over an interpolation pulse produced based on a command block, the numerical controller comprising: an acceleration/deceleration control unit which exercises acceleration/deceleration control processing over the interpolation pulse based on acceleration/deceleration setting corresponding to the command block, and which outputs a first speed pulse; and an overlapping shared acceleration/deceleration control unit which exercises acceleration/deceleration control processing over the first speed pulse based on overlapping shared acceleration/deceleration setting not depending on the command block, and which outputs a second speed pulse, wherein the overlapping shared acceleration/deceleration control unit exercises acceleration/deceleration control processing over the first speed pulse such that a plurality of the command blocks overlap each other. 2 . The numerical controller according to claim 1 , wherein the acceleration/deceleration setting includes an acceleration/deceleration constant time setting or an acceleration/deceleration type setting. 3 . The numerical controller according to claim 1 , wherein the acceleration/deceleration setting is associated with a command type of the command block and/or command speed of the command block. 4 . The numerical controller according to claim 2 , wherein the acceleration/deceleration setting is associated with a command type of the command block and/or command speed of the command block.
