Routing

If the annual volume of a sheet part is ABOVE the Value, recommend the stamping route (M3 with a progressive die, see sheet Tooling) instead of laser plus press brake. Use the annual volume stated on the drawing, not the order quantity.

Routing

When R4 applies: quote the stamping route as the recommended option AND show the laser plus press brake route as an alternative for comparison, with the break-even volume.

Calculation

Laser pierce count: one pierce per closed contour, i.e. every hole AND the outer contour of the part. Number of pierces = number of holes + 1 for a single-blank part. Piercing time is taken from the Speeds record 'Laser pierce' and charged at the M1 rate.
