RENISHAW. apply innovation™ Accuracy at the point of contact

Accuracy at the point of contact Accuracy at the point of contact As industry has developed its requirement for increasingly diverse and complex manufactured parts, inspection systems have had to work hard to keep up. The use of co-ordinate measuring machines (CMMs) with probing systems and in-process inspection on machine tools are two of the solutions offered by Renishaw to help you maximise your productivity and maintain the highest quality. Successful gauging depends very much on the ability of the probe’s stylus to access a feature and then maintain accuracy at the point of contact. At Renishaw,...

apply innovation™ Terminology A Ball diameter C Stem diameter D Effective working length Overall length Renishaw uses a standard description of overall length, measuring from the rear mounting face of the stylus to the centre of the ball. Effective working length (EWL) This is measured from the centre of the ball to the point at which the stem will foul against the feature when measuring 'normal' to the part. Choosing a stylus To maintain accuracy at the point of contact we recommend that you: Keep styli short The more that a stylus bends or deflects, the lower the accuracy. Probing with the...

Accuracy at the point of contact Tungsten carbide Tungsten carbide stems are best used for maximising stiffness with either small stem diameters required for ball diameters of 1 mm and below, or lengths up to 50 mm. Beyond this, weight can become a problem and stiffness is lost due to deflection at the stem to body joint. Ceramic For ball diameters greater than 3 mm, and lengths over 30 mm, ceramic stems offer stiffness comparable to steel but are significantly lighter than tungsten carbide. Ceramic stemmed styli can also offer additional crash protection to your probe as the stem will shatter...

A simple disc requires datuming for only one diameter (usually in a ring gauge), but limits effective probing to only X and Y directions. Adding a ‘radius end roller’ allows you to datum and hence probe in the Z direction, provided that the centre of the ‘radius end roller’ extends beyond the diameter of the probe. The ‘radius end roller’ can be datumed on a sphere or a slip gauge. Rotating and locking the disc about its centre axis allows the ‘radius end roller’ to be positioned to suit the application. Tool setting styli Typically, these are fitted with a square tip and can have threaded or...
