Unfortunatly the ally was 6082 so im gonna get more cut out with 5251.
The material is 1mm thk.
In my naivety i never allowed any forming allowance so there is only around 0.1mm clearance when the blanks are being formed.
What forming allowance should i be working with?
Ill try putting a draft angle on that male tool and see how it goes with the 5251 ally. Will 5 degrees do it?
These will be part of a decorative candle holder. 5 dishes per holder. im hoping to get about £20-£30 each for the unit.
As for the condition of the die: im a supervisor in a small cnc mc shop so cutting those tools was run of the mill, its just the method of forming that has me stumped.
Thanks for the help so far.
