Tip-entry machining of blisks can be practical for shorter blades. Machining blades in a single operation improves efficiency and reduces head movements and chance of collisions.
A new high-accuracy simulation option has been added as part of the advanced simulation module for PowerMill. The system offers an accurate model of the finished part that clearly shows defects in the quality of the surface finish.
Until now, most simulation software has concentrated on preventing part gouging and collisions with the machine tool. The new PowerMill option lets users judge surface quality of finished parts on the computer, spot problem areas, and compare results from different machining strategies.
The software is based on research undertaken by Delcam in association with the University of Birmingham. The system takes into account factors such as cutter geometry and feeds and speeds applied to the toolpath. The result is a realistic simulation.
