Videos Showcase SFP1 Probe
These two videos showcase some of the technology behind the SFP1 surface finish probe option for Renishaw's Revo five-axis measuring head.
The probe in the first video (top) is not the SFP1, but rather, Renishaw's RSP2 tip-scanning probe for dimensional measurement. However, the SFP1 relies on the same laser tip-sensing technology to measure surface finishes ranging from 6.3 to 0.5 Ra.
The second video (bottom) demonstrates how the Revo’s rotary B axis and the SFP1 probe’s passive C axis work together to change the orientation of the stylus.
The irregularity of a machined surface is the result of the machining process, including the choice of tool; feed and speed of the tool; machine geometry; and environmental conditions. This irregularity consists of high and low spots machined into a surface by the tool bit or a grinding wheel.
Measuring workpiece dimensions is relatively simple for machine operators but measuring workpiece geometry which involves more complex comparisons of part shape to an ideal shape--is now also practical on the shop floor. The gaging equipment for doing this is coming down in price while becoming easier to use.
Functional gear testing, also known as total radial composite deviation, is a method of looking at the total effect of gear errors. This test method simulates the conditions under which a set of gears is likely to operate as a result of the gears meshing together.
