CNC Multi-Axis Bending

Bend sequence programming review before first blank is loaded. Sequence is verified for back gauge accessibility on all bends and optimised to eliminate manual repositioning without gauge reference between strokes.

First-off angle verification using calibrated digital protractor on all bend angles before batch production is approved. Any angle deviation outside plus or minus 0.5 degrees triggers bend program adjustment before the batch proceeds.

K-factor bend allowance calculation per material grade and thickness for every new component. Developed length is calculated from the bend allowance data, not estimated, to ensure nominal flange dimensions after forming.

Springback compensation verification on first-off sample. Actual springback is measured against the programmed compensation offset and the program is adjusted if the first-off result is outside tolerance.

Tooling wear monitoring for V-die radius consistency. Worn V-die tooling increases the effective inside bend radius, which affects bend allowance and produces flange length deviation on tight-tolerance components. Die radius is measured at defined intervals and tooling is replaced before the production tolerance limit is exceeded.

Final dimensional audit on finished batch including flange length, overall envelope dimensions, angle verification on all critical bends, and visual check for tool marks, surface damage, and edge condition before transfer to powder coat or dispatch.
