Integrating Robot Programming into the CNC: One Example

For this demonstration, the robot performed both workpiece pallet changeout and simulated polishing operations of machined parts.

I’ve been aware of the capability available with Sinumerik controls for a little while, but I believe the cell below that was in ’s EMO Milan booth represents the first time I’ve seen a demonstration of the concept using an actual machine tool.

The idea is to provide intuitive robot programming capability at a machine’s CNC via the Sinumerik Operate GUI. In the case of this cell, the execution of the movements of the six-axis KR 600 Fortec robot (with 600-kg load capacity), provision of robot safety functions and other robot-specific functions are performed by the Kuka KR C4 robot control. However, that control is connected to the Handtmann five-axis HBZ Trunnion 80 machine’s Sinumerik 840D sl  CNC. Therefore, the machine tool operations and robot program can be tracked and controlled on one screen via parallel channels.

The machine tool operations and robot program can be tracked and controlled on one CNC screen via parallel channels (the robot channel is shown here).

For this demonstration, the robot performed both workpiece pallet changeout (using Schunk clamping systems) and simulated polishing operations of machined parts. Of course, the robot can be used to perform a range of secondary operations, including drilling, brushing and deburring, depending on a manufacturer’s needs.

Check out that shows the cell at the show.
