System information

INTRODUCTION

A group of commands given to the CNC for operating the machine is called a program. By

specifying commands the tool is moved along a straight line or an arc, and machine functions

such as coolant on/off, tool change, or spindle on/off are performed.

The function of moving the tool along straight lines and arcs is called interpolation.

Linear Interpolation Circular Interpolation

When the commanded position to be reached by the tool is executed, the CNC moves the tool to

that position via the circular or linear interpolation modes. The position is given as a coordinate

value in a rectangular Cartesian coordinate system.
