Velocity control
In order to achieve an acceptable traverse rate in the case of very slight motions per block,
an anticipatory evaluation over several blocks (→ Look Ahead) can be specified.
Work offset
Specifies a new reference point for a coordinate system through reference to an existing
zero point and a → frame.
1. Adjustable
A configurable number of settable work offsets are available for each CNC axis. The
offsets - which are selected by means of G functions - take effect alternately.
2. Programmable
Work offsets can be programmed for all path and positioning axes using the
TRANS
instruction.
Working area
Three-dimensional zone into which the tool tip can be moved on account of the physical
design of the machine tool. See → Protection zone.
Working area limitation
With the aid of the working area limitation, the traversing range of the axes can be further
restricted in addition to the limit switches. One value pair per axis may be used to describe
the protected working area.
Workpiece
Part to be made/machined by the machine tool.
Workpiece contour
Set contour of the → workpiece to be created or machined.
Workpiece coordinate system
The workpiece coordinate system has its starting point in the → workpiece zero-point. In
machining operations programmed in the workpiece coordinate system, the dimensions and
directions refer to this system.
Workpiece zero
The workpiece zero is the starting point for the → workpiece coordinate system. It is defined
in terms of distances to the → machine zero.
