What Are The Precautions For Making Sheet Metal

[Grayce Bird]

reasonably select the gap and edging mode. The gap below T = 2.0 is 0.2, the gap between T = 2-3 is 0.5, and the edging mode side milling operation adopts long edge

2.
reasonably consider the tolerance and overall dimension: the negative difference goes to the end and the positive difference goes half; Hole shape and size: the positive difference goes to the end and the negative difference goes half

3.
draw a cross-sectional view in the position and direction of tooth extraction, press riveting, tearing, punch bump (bag)

4
for special angles, the inner radius of the bending angle (generally r = 0.5) depends on the trial bending
