In recent years, high precision and complex shape of press-mold products have been advanced, the demands of mold machining have become more sophisticated. Especially, to reduce manual polishing time, high surface quality machining is required. However, all elements such as machine, control, machining environment, machining program and, etc. are important. OKUMA has been developing not only machine but also electrical components, control devices, and in-house software. Technology in various fields have been developed to challenge high-precision and high-quality machining. We have been working on the implementation of high surface quality machining by providing shape correction function and shape adaptive control function to against surface quality degradation caused by machining program factor. The new “Hyper-Surface” has been developed for more higher surface quality.
1. Newly Developed Machining Program Compensation Function
This function analyzes and corrects machining programs by NC. Including new functions that anyone can easily obtain high surface quality.
1.1 Cutting Line Compensation Function
Estimate the original shape from the command point of the adjacent path, compensate the step of
1.2 Edge Compensation Function
Estimate the original edge from the command point of the edge, compensates a uniform edge
1.3 Command Position Smoothing Function
Detect and compensate micro command position, more smoothly and stabilize speed fluctuation. Also, reduce machining time.
2. Result & Summary
“Hyper-Surface” is possible to compensate machining programs, eliminate cutting line and achieve high surface quality. Higher surface quality machining can be achieved, also can be contributed to the reduction of CAD/CAM program correction cost = work man-hours. We will continue to respond to the customer requests with our various field of technologies.
