1.5. Tool Length Probe

  • File Name: tool-length-probe.ngc

  • Description: Tool Length Probing

This program shows an example of how to measure tool lengths automatically using a switch hooked to the probe input. This is useful for machines without tool holders, where the length of a tool is different every time it is inserted.

1.6. Hole Probe

  • File Name: probe-hole.ngc

  • Description: Finding the Center and Diameter of a hole.

The program demonstrates how to find the center of a hole, measure the hole diameter and record the results.

1.7. Verktøykompensasjon

  • File Name: comp-g1.ngc

  • Description: Entry and exit movements with compensation of tool radius.

This program demonstrates the peculiarity of the toolpath without and with tool radius compensation. The tool radius is taken from the tool table.

2. Lathe Examples

2.1. Threading

  • File Name lathe-g76.ngc

  • Description: Facing, threading and parting off.

This file shows an example of threading on a lathe using parameters.
