摘要:
A load cell is used as a normal force transducer for monitoring the interface contact force between a superabrasive grinding wheel and a workpiece. A computerised numerical control varies the relative feed rate between wheel and workpiece in response to the contact force.
摘要:
A grinding machine utilises a gantry type loader (27) for exchanging workpieces (12, 12a) with the work support spindle (11.) of the machine. The loading head (33) of the gantry loader has a rotatable workpiece gripper assembly (34) to switch the parts end-for-end during the loading and unloading process. The loading head is also fitted with non-rotating tool grippers (36) which are spring biased to mechanically grip and extract a grinding wheel tool (24) from a grinding wheelhead (13) and exchange the tool (24) with a different tool located in a tool support pocket (54) of a tool storage matrix (37) at a position remote from the grinding wheel head (14).
摘要:
Two objects, typically a tool (44) and a workpiece (45), are moved towards one another as the sum of the rates of motion produced by two independent drive means (21,22), the rate of approach being the difference between the rates at which the two drive means operate, whereby precision of approach of movement may be obtained.
