Machining Workstation
The workstation station contains a 5-axis robot and two CNC machines — a 2-axis turning center and a 3- axis machining center. Both CNC machines are equipped with an automatic tool changer (ATC). The robot loads and unloads parts to and from the CIM conveyor and tends the CNC machines. To provide mobility and increase its work area, the robot is mounted on a linear slide base. The SCORBOT -ER 9 is a continuous path robot whose axes are driven by DC servo motors with optical encoder feedback. The robot’s real-time, multi-tasking controller supports up to 12 axes, and 16 inputs and 16 outputs for communication and synchronization in the FMS and CIM cells. The controller’s internal programming language provides all the functions and commands required for programming and operating a robotic work cell. A hand-held teach pendant enables direct operator manipulation of the robot and peripheral axes, position recording and other work cell functions. Both the proLlGHT 1000 and the proLlGHT 3000 are tabletop CNC machines. Similar to larger industrial machines, the proLlGHTs use EIA, ISO, and Fanuc-compatible G and M code programs to cut parts in a variety of materials. The machine’s software supports a number of programming modes, multiple tool programming and canned cycles. The FMS station allows students to study and acquire skills in the use of CAD/CAM software, as well as robotic and CNC programming and control. Moreover it gives students experience working with automated systems. The robot and the machining center can be operated as stand-alone systems in addition to the integration and use as an FMS cell within the CIM system.
