What are the major stages in progressive die design?
Product design
Blank size design
Strip layout design
Die Design
Die design flow
What does shape tolerance define?
Allowable range of shape
Cutting clearance
Positioning tolerance
Surface finish
What is the importance of burr direction in product design?
What are the examples of positioning tolerances?
Parallelism
Perpendicularity
Concentricity
Symmetry
Roundness
What factors are involved in estimating blank size design?
What factors should be considered in strip layout design?
Stamping machine specifications
Production method
Feeding method
Production volume
Product ejection method
What is the significance of the cutting clearance in product design?
What is the formula for calculating Cutting Force (CF)?
CF = l × S × τmax
CF = S × τmax
CF = l × τmax
CF = l + S + τmax
What is the formula for calculating Cutting Clearance (CC)?
CC = C × S × ∛τmax
CC = C × S × √τmax
CC = C + S + τmax
CC = C × τmax
What is the formula for calculating Economy Factor (E.F)?
E.F = PRODUCT AREA × LINE NO.PITCH × STRIP WIDTH x 100%
E.F = PRODUCT AREA + LINE NO.PITCH + STRIP WIDTH
E.F = PRODUCT AREA / LINE NO.PITCH / STRIP WIDTH
E.F = PRODUCT AREA - LINE NO.PITCH - STRIP WIDTH
What is the relationship between the thickness of the die plate (H) and the Cutting Force (CF)?
What is the minimum distance for screw size M4?
15 mm
25 mm
40 mm
60 mm
