Programming a Zhongrui CNC press brake involves systematic steps for accuracy. Start by importing the 3D model of the part into the CNC control system (e.g., Cybelec ModEva 12) via CAD software (STEP/IGES format). Define material properties (thickness, yield strength) and select appropriate tooling (punch/die type, radius). The software automatically generates bend sequences, but manual adjustments can optimize for minimal tool changes. Set bend angles, backgauge positions, and ram speed based on material behavior, using the built-in springback compensation calculator. Perform a simulation to check for collisions and verify bend order, then save the program with a unique identifier. For repeat jobs, recall stored programs and adjust parameters as needed, ensuring consistency and reducing programming time by 80% for batch production.
