This is a sort of generic question but since I am running an OMD based machine it could be a good place to discuss this.
I recently adopted DNC operation. The machining operation is smooth but I see slow operation on the complex parts of 3D cuts. Reading articles on DNC suggests that the machine operating speed can be increased by changing various parts of the system but what is really limiting cutting speed? It seems to me that the hardware of the mill would be the limiting factor since it is mechanical whereas the rest of the system is electronic.
So, we have the movement speed of the mechanics of the mill itself, the rate at which the internal CNC computer can operate, the rate at which we can send the G-code over a serial cable and the speed of the DNC computer. Which of these is the limiting factor in an OMD system and what system improvements could help to speed up 3D cuts?
Any insight would be appreciated.
