Interferometric Non-Contact Measurement of the Change in Cutting Depth of the Workpiece on CNC Milling Machines

43956

With respect to measurements made by use of light source in the manufacturing metrology, the conversion of the mechanical values to the electronic ones and then transfer of the results to PC provides a number of advantages for the manufacturer. The reason is that the measurement systems with use of light source are both non-contact and high precise, making instant processing by the computer. Furthermore, it also provides great convenience for measurement of the workpieces, which are physically hard to measure. This study concerns a system to measure the changing value in the cutting depth on basis of Michelson interferometry measuring mechanism during the milling of plane surfaces on the milling machines, which take an important place in the machining industry. An electronic fringe counter is designed in order to count the fringe obtained by the Michelson interferometry. The cutting depth value entered in the system by use of Sim CNC, which controls the milling machine and the measurement value obtained by the laser measurement system as a result of the process were compared and the differences of 7% between them were interpreted.
