Question: A circular shape blank will be cut of (100 + ) mm diameter from a strip of (2.8 + N mm with 100, a clearance value of 0.25 mm. Take the shear strength as 400 MPa. Determine a) The appropriate punch diameter. b) Blanking force. c) Blanking force when the blade angle is (5 + 100. Notes: - Never change the template and only write your own identity data. - Your N value is in the list below and is unique to you.
Theory and Design for Mechanical Measurements
Measurement is a term that refers to analyzing a manufactured component regarding the degree of accuracy for dimensions, tolerances, geometric profile, roundness, flatness, smoothness, etc. Measurement always involves comparing the manufactured component or the prototype with a standard specimen whose dimensions and other parameters are assumed to be perfect and do not undergo changes with respect to time.Precisely in mechanical engineering the branch that deals with the application of scientific principles for measurements is known as metrology. The domain of metrology in general deals with various measurements like mechanical, chemical, thermodynamic, physical, and biological measurements. In mechanical engineering, the measurements are limited to mechanical specific such as length, mass, surface profile, flatness, roundness, viscosity, heat transfer, etc.
Basic principles of engineering metrology
Metrology is described as the science of measurement, precision, and accuracy. In other words, it is a method of measurement based on units and predefined standards.
The first solution shows that the formula is summed and multiplied in parentheses, but when applying the formula, it is multiplied and added. Can you check this is an error? And (N=11)
