H1: Manual and handwheel travel

3.1

Introduction

3.1.1

Overview

Even on modern, numerically controlled machine tools, a facility must be provided that
allows the user to traverse the axes manually.
● Setting up the machine
● Retraction of the tool after a program abort
Functions
The following functions are available to manually traverse axes:
● Continuous traversing in jog or continuous mode
● Incremental traversing in jog or continuous mode
● Traversing of axes via electronic handwheels
● Handwheel override in AUTOMATIC mode with path specification and/or velocity override
● Correction of the tool wear for machining in AUTOMATIC mode by means of additional
● Approach of fixed points specified via the machine data
● Retraction movement in the tool direction after a program abort due to a power failure or

This is especially necessary when a new machining program is being set up and the
machine axes have to be moved with the traversing keys on the machine control panel or
with the electronic handwheel. Where coordinate offset or rotation is selected, manual
travel can even be performed in the transformed workpiece coordinate system.
After a program abort due to a power failure or RESET, the operator must manually
retract the tool from its current machining position. This is usually done by operating the
traversing keys in JOG mode. The transformations and coordinate systems used for
machining must remain active while this is done.
