Control of Analogue Scan Probe in CMM Inspect of Spiral Bevel Gear

Abstract

In the context of three-dimensional 3D coordinate metrology, CMM (coordinate measuring machine) have been widely adopted as general-purpose tools that have the capability of inspecting various mechanical components having complex topology and geometry. The recent developments in spiral bevel gears (SBGs) manufacturing system have made the traditional dimensional inspections bottlenecks in the production line. To overcome these bottlenecks, computer integrated dimensional inspection was proposed with the CMM being the key device. In this investigation, a framework for integrating the CMM into CAD/CAM environment is developed. In order to achieve a higher level of automation, CAD-directed inspection planning is essential. First of all, due to the distinct characteristics of various probes in terms of resolutions, digitizing speed and spatial range, The CMM probes have to be selected and controlled properly. A motorized head gives a DCC CMM the added capability of probe reorientation, allowing the probe to inspect features at the optimum angle, considering access requirements and probing best practice. An algorithm to generate an optimized control of analogue scan probe in CMM inspect of spiral bevel gear is proposed. The proposed algorithm is implemented using PC-DMIS as the CMM software system and PH10M+SP600M as the analogue scan probe system. The effectiveness of the proposed algorithm is verified by the results of the implementation
