Abstract
A controller performs gap control such that a Z-axis position of a tip of a cutting head of the machine is not below a preset lower limit position while keeping the distance between the tip of the cutting head and a workpiece constant. The numerical controller calculates a substantial lower limit position based on a detected state of the workpiece and the preset lower limit position. If the Z-axis position of the tip of the cutting head is below the calculated substantial lower limit position, it is compensated so as not to be below the substantial lower limit position.
