Optical Post-process Measurement System<br />
for PETER WOLTERS <strong>DDG</strong> Machines<br />
Non-contact thickness measurement<br />
PETER WOLTERS GmbH has developed a non-contact<br />
system for measuring component thickness as an alternative<br />
to conventional mechanical-measurement systems.<br />
This system eliminates the disadvantages associated<br />
with mechanical measurement, such as measurement<br />
errors caused by measuring-tip wear, as well as possible<br />
scratch marks on the work piece surface. It also makes<br />
it possible to measure the thickness of components<br />
with special surface contours, such as holes, grooves,<br />
notches, and embossing, as well as extremely thin-walled<br />
workpieces. The system employs optical measurement,<br />
compensating for the above-mentioned disadvantages<br />
associated with the tactile systems that have been used<br />
to date for post-process measurement. At the same time,<br />
integrated compressed-air nozzles protect the optical<br />
path between the sensor and the work piece surface and<br />
provide a targeted airflow that prevents unwanted work<br />
piece movements and cleans the measuring surface.<br />
Sensor Technology for the Optical Measurement of<br />
Grinding-wheel Position in a PETER WOLTERS <strong>DDG</strong> <strong>600</strong><br />
This measurement system makes it possible to measure<br />
the lower grinding-wheel surface up to a grinding gap of<br />
2 mm. The grinding-wheel position is detected by means<br />
of optical distance measurement during the grinding process<br />
at peripheral speeds of up to 60 m/s. With reference<br />
to a representative grinding-wheel radius, this measurement<br />
technology can be used for a control system that<br />
keeps the position of the lower grinding wheel constant.<br />
With a second, separate control system, the position<br />
of the upper wheel can be adjusted by means of postprocess<br />
thickness measurement. With this system, the<br />
optimal grinding-gap position can be maintained for a<br />
long period of time.<br />
This technology offers the following advantages:<br />
• Reduction of grinding-wheel wear<br />
• Reduction of costs for dressing tools<br />
• Increased output owing to a reduction of non-productive<br />
times<br />
