1.	Die punch clearance is generally very critical for blanking as well as for punching operation.(a) True(b) FalseThe question was posed to me during an interview.Query is from Blanking and Piercing in chapter Forming Process of Casting-Forming-Welding II
Answer» Right answer is (a) True The explanation is: Punching is basically a kind of shearing operation in which the required part is the SHEET left out after making a punch hole in the metal sheet. This method is also KNOWN as contour shearing. Die punch clearance is generally very critical for BLANKING as well as for punching operation, as it maintains the kind of finish obtained on the FINAL part.
