Example text

Modern communication networks enable economical and fast data communication from sensors to the controller. With the recent advances in computer and sensor technology, combining sensors with an open architecture PC-based CNC machine tool controller becomes more viable. Simple sensors, such as tool breakage monitors, are already part of a machine tool control system. 3D vision systems and image processing techniques are being studied to perform in-cycle part measurement as well as tool flank wear monitoring.

In a fixed tool head polishing system, the contact force depends on the physical characteristics of the contact wheel and the belt, and the robot endeffector displacement. The force control can be realised by controlling the vertical movement of the workpiece against the contact wheel. However, 32 X Q Chen, Z M Gong, H Huang, S Z Ge, and L B Zhou further studies show that the force control stability cannot be easily achieved. One reason is that the wheel stiffness is not constant over the desired displacement range.
