Renishaw

Description
The Renishaw head is an electronic auto-detecting head for the Coordinate Measuring Machine (CMM). It is an add-on for the CMM which increases utility and simplifies operation (especially for a single operator).

Principle Uses

 * Simplifies CMM operation
 * Easy reorientation and angling
 * Selection of small probe-tips

Principles of operation
The Renishaw uses electronics to immediately detect tiny deflections of the probe (upon contact with a solid surface). It passes this detection to the CMM and records a hit. This eliminates the need for the operator to manually press the record/measure button.

Renishaw tips/reminders

 * Tip can rotate and change angle
 * Needs to be recalibrated each time
 * Don’t hold the head while moving
 * Deactivate auto-detect if moving quickly moving into a tight space
 * Basic head better for determining center of small holes
 * Always verify direction of measurement (inside/outside radius)
 * SLOWLY approach surfaces
