This provides the facility to change stylus configurations either manually or automatically without the need for requalification of the stylus tips, thereby giving significant time savings in inspection routines.

Modules offering a range of trigger forces allow the probe performance to be best matched to the measurement task. A set of probe extensions is also available, as is a 6-way module. The stylus mounting thread accepts styli from the Renishaw M2 range.

The TP20 system is easily retrofitted and is compatible with existing touch-trigger probe interfaces, extensions and adaptors.

TP20 probe system

The TP20 is a touch-trigger probe that gives its users the ability to change stylus configurations manually or automatically, without re-qualification. The TP20 is now widely accepted as the industry standard replacement for the TP2-5W probe, offering a range of new benefi ts. It can be easily retrofi tted to manual and DCC co-ordinate measuring machines (CMMs).

The range of modules

A range of seven, application specifi c, stylus modules is available: The low force module (LF) for high accuracy with short styli and delicate materials.

The standard force module (SF) is suitable for most applications.

The medium force module (MF) is suitable for vibration resistance when using longer styli.

The extended force module (EF) is suitable for very large stylus arrangements.

The 6-way module (6W) for measuring grooves and undercuts, has signifi cantly improved metrology performance over the TP2-6 way.

Two extension modules (EM1 and EM2) improve reach and offer better metrology performance than using equivalent length styli.

Probe extension modules

The EM1/EM2 extension modules increase probe reach, allowing the inspection of features with restricted access. The extensions available are 70 mm (EM1) or 95 mm (EM2). The standard trigger force module is integral to both EM1 and EM2. The use of an extension module gives improved metrology performance compared to using the equivalent length of stylus with a standard length module. The ability to change modules without re-qualifi cation and to automate the changing process (using the MCR20 rack), offers advantages over the use of existing probe extension bars, such as the Renishaw PEL1.

Fast, repeatable stylus changing

The MCR20 module change rack The optional MCR20 module changing rack has the capability of storing up to six probe modules for automatic changing under measurement program control. Probe triggers are inhibited during module changing by a proximity switch system when using a TP20 probe body. When using a TP20 NI probe body the probe trigger must be inhibited through the software. Therefore, the MCR20 rack is passive and does not require an electrical connection to the CMM. The MCR20 is designed to securely hold the stored probe modules and to protect them from contaminants that may be present in the working environment.

The MSR1 module storage rack

The MSR1 can store up to 6 probe modules for manual stylus changing and safe keeping when not in use. Pre-qualifi ed stylus arrangements on probe modules can be selected and switched when needed.
