Roughness Sensor Enables the Inspection of Surface Waviness
The Zeiss Rotos roughness sensor enables coordinate measuring machines (CMMs) to inspect surface waviness and roughness, even on complex workpieces, in a single measurement run without any reclamping. This ability speeds up the measurement of all surface parameters.
The sensor enables the user to check the size, form, location tolerances and roughness parameters on a single machine. With the sensor, the Prismo and CenterMax CMMs eliminate the need to use separate stylus instruments to capture significant form deviations. The user can exchange the sensor as needed using an interface on the CMM probe.The sensor also enables the user to capture Ra roughness values ranging to 0.03 µm.
The Rotos sensor enables the inspection of nearly all workpiece characteristics. Because of the sensor’s three rotatable, multiple-stylus arms, the user can measure deep bores, overhead areas and other difficult-to-reach surfaces. Surface roughness, size, form and location can be analyzed and visualized in a customized display in PiWeb reporting.
New features include skidless styli intended for measuring roughness and waviness on sealing faces. The company says that programming the surface parameters is quick and easy because the sensor is completely integrated in Calypso, the company’s measuring software.
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.
Simple "roughness" measurements remain useful in the increasingly stringent world of surface finish specifications. Here's a look at why surface measurement is important and how to use sophisticated portable gages to perform inspections on the shop floor.
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.
