Research on the Plan for NC System Based on STEP-NC
Key Engineering Materials, 2009To resolve the problems aroused by G code in manufacturing industry, a plan for NC system based on STEP-NC is proposed. The whole system is designed into two parts: system software and system architecture. With modularized design thinking, the control software includes five modules: interpreting module, man-machine interface, task coordinator, axis ...

Separation of the monotone NC hierarchy
Proceedings 38th Annual Symposium on Foundations of Computer Science, 1999The class monotone-\(NC^i\) is the class of all functions that can be computed by polynomial-size circuits of depth \(O(\log^in)\) over the monotone base \(\{\wedge,\vee\}\). It is shown that, for all \(i\), monotone-\(NC^i\) is a strict subclass of monotone-\(NC^{i+1}\), and, thus, monotone-\(NC\), the union of the classes monotone-\(NC^i\) over all \(

The NC Grinding Machine Rebuilding for TG30 NC Lathe
Advanced Materials Research, 2013Based on the characters of NC lathe and NC grinding machine, the NC grinding machine rebuilding for TG30 NC lathe is studied in this paper. According to the geometric parameters of grinding, choose appropriate TG30 NC lathe, keep the driving system of spindle and the feeding function of two axle linkage of NC lathe, increase the high speed rotating ...
