The Research on the the Test System for Punch of CNC;

The author conducts a complete and detailed theoretical analysis on the causes of raised grain defect during the fabrication of lattice mesh plate in the numerical control small punch spinning drying equipment in the article.

A new type of visualized NC programming system for punching machines in which the PM and the SM are closely integrated is developed.

For CNC system of full automatic NC punching machine, electromagnetic noises are analysed in detail and several measures of anti-disturbance is proposed, including power supply de signing,electronic line designing,grounding,shielding ,isolating,filering, etc.

This newly designed punch machine can automatically separate the inner and outer ferrules form 608 to 6202 bearing series, and can process 20 to 30 sets per minute at least.

This paper presents an improved numerical control feed system based on a traditional punch machine and the detailed explanation for such hardware system as structure,control and feed bench.

PLC control of JH23－63 punch press;

Necessity that PLC is used in the punch press control is pointedout.

Classification model of man-hand and billet based on BP algorithm in safety protector for puncher;

This paper brings up the research on the punching machine protecting technology which is the design of high reliability automatic protection system for stamping machine based on safe light screen from a different point of view from other research methods.
