Function
Function Function Function
The tool is moved at the highest possible speed (rapid traverse). If the rapid traverse
movement is required to execute simultaneously on several axes, the rapid traverse speed is
decided by the axis which takes the most time. The operator can use this function to position
the tool rapidly, to travel around the workpiece, or to approach the tool change position.
Example
Example Example Example
Move tool from P1 (45, 90) to P2 (10, 20) at the rapid traverse speed.
