Okuma Technology Premium Solutions
Auto machining data compensation, easy and improved die/mold surface quality
Hyper-Surface, in addition to the Sculptured-Surface Adaptive Acceleration Control featured in the
previous Super-NURBS, detects CAM-output machining data “disturbance,” and corrects that on the
Okuma CNC to improve surface quality while maintaining the required shape accuracy.
- Production floor issues
- Machining data command-point
disturbance adversely affects
surface quality -
- ・Machining data variations result in scratches on the machined surface.
- ・Correcting the supplied data is difficult.
- ・Removing cutter marks by hand finishing and polishing is time consuming.
- Machining data command-point
- User benefits
- Better surface quality without modifying the machining data
-
- ・Eliminates the time required for hand finishing.
- ・Reduce scratches and uneven edges.
Eliminating variations in command position and feed rate improve machined surface quality
Automatically corrects for small variations in machining data command positions of output from a CAM processor.
And passing speeds for each cutter path at corners are made consistent.
That stabilizes feed rates and improves surface quality.
