Using measurement and software to optimise part setup for machining
DELCAM PLC - United Kingdom
Machining operations require a known part setup and datum. Traditionally this is achieved by physical adjustment of the part- making iterative adjustments until it is in the desired location. This requires skill and patience, and the time required is unpredictable, making the process unsuitable for lean manufacturing.
Machine tool probing can be used to improve the setup process. A measuring probe fitted to the machine tool allows measurement of the part in workpiece coordinates, and the results can be used to adjust the workpiece position. This has usually been limited to measuring simple features due to the difficulty of creating suitable probing cycles. The presentation describes how an integrated solution- combining measurement on a machine with the probing and alignment techniques from inspection software- has led to dramatic improvements in setup time and consistency.
