Numerical controller including overlap function between arbitrary blocks by common acceleration/deceleration control unit

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.
