I. The Process of Metal Bending using CNC Machines (250 words):
Bending metal with CNC machines involves several essential steps that enable accurate and repeatable results. Firstly, a precise digital model of the desired shape is created using Computer-Aided Design (CAD) software. This digital blueprint serves as a guide throughout the production process. Next, the CAD design is converted into computer code that coordinates the movements of the CNC machine's hydraulic or electric press brake.
The material to be bent is placed on the press brake's bed, securely fixed to prevent movement during bending. Then, utilizing a series of programmed instructions, the machine applies pressure to specific points along the metal sheet, gradually bending it to conform to the desired shape outlined in the digital model. Accurate positioning of the material allows for consistent bending angles and accuracy within tight tolerances.
