The effects of roller conveyor on muscle activity in workpiece loading on CNC machining centre: a preliminary study

In the recent years, Advance Manufacturing Technology (AMT) has been widely used in manufacturing industry to increase manufacturing process capability. However, Computer Numerical Control (CNC) machine designs have only focused on its operational capability. The harmonious coordination between u...
