PROBING IN MACHINE TOOL

Measuring in
machine tool
Tool or workpiece touch probe from any manufacturer can
be connected to NCT 200 controls by ETP card. MES soft-
ware integrated in control manages high variety of touching,
measuring functions, the DIGI program package touches con-
trol path and complex surfaces. Some manufacturers (REN-
ISHAW, M&H) offer software packages for their touch
probes. These MACRO programs can also be installed in
NCT controls.
Tool
measurement
The tool is essential to ensure machining accuracy of the
workpiece. The tool geometry can be measured quickly and
safely by doing measurement in machine tool. Tool dimen-
sional changes caused by tool wear can be managed by
programmed measurement cycles during machining and tool
wear or breakage of tool can also be inspected.
Tool measurement can be also performed on stationary or
driven tools. Mechanic or laser device of several manufac-
turers (HEIDENHAIN, RENISHAW, M&H) can also be in-
stalled to NCT controls.
Workpiece
measurement
Although workpiece touch probe is traditionally used for quick
and accurate probing of workpiece zero point, the demand
increases for measuring workpiece during machining. During
machining the geometry of workpiece could change signifi-
cantly and the necessary accuracy could not be ensured with-
out measurement during interruption of machining, because
of internal structural transformations.
Measurement cycles could be used for the most frequently
used measuring tasks (shaft, bore, corner point, etc.). Coor-
dinate transformation after measurement provides the accu-
rate machining for incorrectly clamped workpiece.
Measuring and calibrating rotating axes of 5 axis machine
tools have done quickly and easily by measurement in ma-
chine tool.
Digitizing
Digitizing inside of machine tool is actually a series of meas-
urement. Software module integrated in control drives the
workpiece touch probe along the workpiece contour in range
defined by cycle parameters. In touching points the coordi-
nates of touching sphere central point saved in technological
program specified by operator. In this method a contour re-
ceived is parallel to the original, that is generated by using
CAD/CAM software.
