Materials Tester Checks Quality In Advanced Metrology Systems

LFPlus single column materials testing machines from Lloyd Instruments have been integrated into manufacturing cells at Renishaw. The LFPlus is used to make custom designed materials tests on Renishaw's SP25M scanning probe system. Each instrument is equipped with NEXYGEN MT materials test and data analysis software and Ondio application builder software which integrates seamlessly into Renishaw's internal production software control system. This allows a variety of different testing parameters to be collated into the pass/reject criteria for the component. The LFPlus is used to perform a number of tests. These are: travel tests, spring rate testing (in X, Y and Z axes) and a breakout test for the kinematic couplings. Breakout tests are performed by holding the assembly horizontally in a special jig mounted on the instrument baseplate and applying a force to the end of the stylus until the kinematic coupling detaches. The system records the maximum force required. Spring rate (change in load per unit deflection) is measured on three welded, chemi-etched springs used in the stylus module. Spring rate is determined by measuring the force required to deflect the spring by predetermined percentages, together with the spring extension resulting from the applied force.
