Studer Laser System Efficiently Measures Small Batches
Studer’s laser measuring control system can generate thousands of measuring points for evaluation, even with the workpiece rotating, reducing measuring time.
New laser measuring technology from Studer is designed to increase reliability and productivity for finishing processes on grinding applications with exacting tolerances and highly accurate surface qualities. Tools that require this tolerance range of dimension, form and position accuracies are often sensitive to tactile measurement. While companies typically have empirical values against which to measure these products, they may not have been able to measure small-batch products without time-consuming trips to intermediate measuring devices. This laser measuring control system can provide an efficient solution.
Operators mount the device mechanically and can adapt its size to the workpiece diameter. The existing air nozzles for blowing off the workpiece during measurement and the dirt screens protect the laser optics from lubricant in the machine. In comparison to previous models, this system’s lasers are said to have more accurate laser optics. According tot he company, the device can generate thousands of measuring points for evaluation, even with the workpiece rotating, reducing measuring time.
Not only does this system record different diameters, but it can carry out control measurements on interrupted diameters, such as shafts with keyways or longitudinal grooves and toothed gears in the diameter range. It omits setup and resetting of previously-used tactile in-process gauging devices, increasing efficiency. Users can select the measuring cycle after each machining operation or at the end of the grinding process. Studer’s software logs the measured values per diameter after each measuring cycle. This process enables the operator to ascertain the quality of the ground component at a glance.
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.
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.
Guidelines used to standardize the measuring process can provide a good basis for making gage decisions.
