Rapid Sheet Metal Prototyping: Where the Process Changes as Quantity Grows
Where the Process Changes as Quantity Grows
Before you release the project
- Define the function, environment and the question this batch must answer.
- Specify material grade, geometry, quantity, finish and the dimensions that control fit.
- Agree the inspection method and the evidence required to accept the parts.
- Record the drawing revision and approval before production begins.
Common planning questions
What files are useful for a sheet metal quote?
Supply the 3D model and controlled drawing with material, thickness, quantity, bend and joint requirements, finish and critical assembly dimensions.
Can tight tolerances be applied to every bend?
Bend variation and the assembly datum scheme must be considered together. Focus tighter limits on functional interfaces and agree a measurement plan.
