Easy FIX case history: polystyrene milling.
Wednesday, 13 January 2010 11:40

In that proof Easy FIX is been used to optimize the robot milling process.
The used robot is a MOTOMAN, with NX100 controller, that was offline programmed using a CAD / CAM system and a post-processor simulator.
The rough size was 350(mm)x350(mm)x600(mm) and the used material was polystyrene
.

 

Roughing
It's been made the CAM roughing program using a tolerance of 0.01mm and a fedrat speed of 10000 MMPM.
After the simulation and post-processor steps the program was executed by the robot and the piece was done.


Optimized roughing
The CAM program has been optimized using Easy FIX and a tolerance of 0.5 mm. The simulated and post-processed program was executed on the piece already roughed.
Result: The final savings in terms of processing time was 63%. The CAM trajectories
have been retained despite points reduction.
 
 

Finishing
It's been made the CAM finishing program using a tolerance of 0.01mm and a fedrat speed of 10000 MMPM. After the simulation and post-processor steps the robot has executed the program failing to maintain the programmed speed because of the very close points
.

Optimized finishing
The CAM program has been optimized using Easy FIX and a tolerance of, at the end, 0.5 mm. The robot, thanks to Easy FIX optimization, has maintained the programmed speed.
Result: The final savings in terms of processing time was 82%. The surface finishing degree of the CAM program was successfully maintained despite the points reduction.
