With nc cutting plate machine, CNC punch, CNC bending machines, CNC machine circle round, nc thermal machine, CNC laser cutting machine and a series of advanced numerical control equipment.

By means of com programming, the bending and plane geometry feature recognition of blank layout for the car punch parts were completed in blank layout optimization.

Strength checking formula for blanking punch in current documents have been reviewed and the anti-bending ability of blanking punch is discussed.
