Inspection Planning Strategy for the On-Machine Measurement Process Based on CAD/CAM/CAI Integration

The objective of this research is to develop an effective inspection planning strategy for sculptured surfaces in the OMM (on-machine measurement) process. As a first step, effective measuring-point locations are determined to obtain optimum results for given sampling numbers. Two measuring-point selection methods are suggested in this study based on newly proposed CAD/CAM/CAI integration concepts: 1. By the prediction of cutting errors. 2. By considering cutter contact points to avoid the measurement errors caused by cusps. As a next step, the TSP (travelling salesman problem) algorithm is applied to minimise the probe moving distance. Appropriate simulations and experiments are performed to verify the proposed inspection planning strategy in this study, and the results are analysed.
