Which stages are involved in the sheet metal blanking process? Select one O a Deformation relaxation and separation Ob Metal self-bending, fracturing and separation OC Plastic deformation fracturing and separation Od separation, followed by large scale plastic deformation What are the key geometrical parameters in punching? Select one: Оа. Punch diameter, die diameter and clearance between the die and the punch O b. Punch height, die diameter and clearance between the die and the punch OC. Punch height, die height and die diameter Od Punch diameter, die height and clearance between the die and the punch Which of the following statements is correct? Select one O a Large cutting clearance leads to a straight cutting line Ob Small cutting clearance results in low cutting force Oc In case of too large cutting clearance there will be large plastic deformation in the sheet metal before the fracture initiation Od Very small cutting clearance leads to only one fracture line in the cutting section Which are the basic geometric parameters in the sheet metal bending? Select one: O a Sheet length angle and sheet thickness Ob Bending speed, temperature and force applied Oc Bend position, load applied and speed of releasing the force Od Bend radius, bend angle and sheet thickness
