Bending is a machine tool used to bend sheet metal into various forms and shapes. Some operators improve their skills through trial and error at work, while others receive formal training and obtain industry certification. However, no matter how the operator learns trade, he should have a keen understanding of the four main areas of the operator's role, drawings, bending machines and tools.
Excellent operators should always hone their skills through additional training and the implementation of new industry technologies. Operators should fully understand the entire manufacturing process, including machine settings, manufacturing time required to meet job specifications, and machine functions.
Tools with poor part quality are not acceptable. It is almost impossible to make high-quality parts with bad tools. Different types of bending machines require different types of tools, and operators must fully understand the tolerances of each punch and die used.
All important information required to make the part should be included in the drawing. Among them, include the bending angle, part size, inner radius of the bend and the appropriate tolerance of each part.
Bending machine type
Bending machine types include mechanical, hydraulic, retrofit CNC and full CNC brakes. Each machine type has its own functions, limitations and set-up time. CNC tube bending machine operators must fully understand the differences of each machine, the forming time of each machine, and the concentrated load limit associated with each tool.
