Measuring in JOG

4.1

Overview

4.1
General information
There are two types of measurement: Workpiece measurement and tool measurement.
These measurements may be undertaken
• automatically
• semi-automatically in JOG mode.
The following chapter describes semi-automatic measurement for milling technology:
measuring in JOG.
Workpiece measurements
Workpiece measurements may include:
• Calibrating the workpiece probe.
• Measuring the contour elements on a workpiece (edge, corner, hole, spigot, rectangle)
Tool measurements
Tool measurements may include:
• Calibrating the tool probe.
• Determining the tool length or radius of milling tools, or tool length of drills and then
General sequence
The required function is selected via softkeys on the HMI in JOG mode. Input displays are
shown. These have to be completed via screen forms. This describes the measurement
tasks and selects the offset.
The user must put the tool or probe into a permissible starting position for the measurement
task, e.g. using the traverse keys or handwheel (manual traverse).
Once you have pressed the "NC start" key in JOG mode, the remaining sequence is
automatic.
