Probing systems forco-ordinate measuring machines

Introduction to CMM probing Contents 1
CMMs are used for a wide variety of industry applications,especially for post-process inspection of manufactured components. Renishaw’s probes and probing systems have become the industry choice for rapid and accurate inspection. CMMs, which act as a quality reference, use probing systems to replace traditional manually operated measuring instruments such as micrometers, vernier callipers and dedicated gauges.

Fitting the probe on the CMM 5 Manual probe heads
The probe is mounted on the CMM via a probe head. The type of head is determined by the flexibility and automation required.Renishaw has designed a range of probe heads for manual and automated systems.Motorised heads maximise probing efficiency and give a3-axis CMM, 5-axis capability. A motorised head can also be used with Renishaw’s autochange systems which allows rapid and automatic exchange of multiple probe types and extension combinations. with integral M8/autojoint probe mount 6 Manual probe heads

Traditionally, scanning has been limited to relatively slow machines but Renishaw’s universal CMM controller family enables this function at speeds many times faster than was previously possible. indexing type 9 Interfaces and controllers

The range of accessories enhances the basic system by offering additional capability such as stylus changing for the probe, probe sensor changing for multiple probe requirements and extension bars to provide access to deep features.Renishaw supplies a comprehensive range of styli forcomponent inspection and scanning applications which are available in a variety of profiles, sizes and fittings to best suit the probe employed and the components’ features and dimensions.To avoid the risk of compromising measurementperformance, always use a replacement stylus from Renishaw! for autojointed probes/extensions 11 Extension bars 12 Shanks 13 Accessories 14 Styli and custom design service 15 Glossary of terms 16 Product index
