The conveyer Feeds the work piece to the next stopper. Depending on the can Figuration thiscould be the last process step or the workpiece could be Forwarded to the next station. 6. Lather parts 7. This process steps concern system con Figurations that contain more than one machine. AFterthc lathing process the work pieces a re transported to the next sta tion either by the robot with its linear slide unit . model MTLR5 or by an additional conveyor belt connecting both production cells . model MT2R5 .The steps 2-5 are repeated with the second machine. 35 Cac he dieu khien so He thong tich hop CIM Computer Integrated Manufacturing Là sự liên kết toàn bộ giữa CAD và CAM vào một quá trình giám sát và điều khiển hoàn toàn bằng máy tính jA General View of Some important CIM Subsystems.
