5. What are the adverse effects of tool wear in cutting processes?

If you were manufacturing a component with a minimum thickness of 1mm and a tolerance of 0.1mm (or better) which method may be appropriate to achieve this?

1) The stresses and strains in metal forming are of which type? Elastic_plastic_ultimatefracture_none of these 2) The applied stresses in most bulk deformation processes are- Shear_tensile_compressive_bending_none of these 3) What is the difference between the physical shape of bulk deformation and sheet metalworking manufacturing processes?. In bulk deformation, the work parts have a. area-to-volume ratio, whereas in sheet metalworking, the area-to-volume ratio is Low, high_high,low_high,high,low,low 4) is a bulk deformation process in which a workpiece is compressed between two opposing dies, so that the die shapes are imparted to the work. Rolling_forging_drawing_extrusions_none of these 5) is a compression bulk deformation process in which the work material is forced to flow through a die orifice, thereby forcing its cross section to assume the profile of the orifice Forging.extrusion_drawing.extendingrollingnone of these 6) is a bulk deformation process in which the diameter of a…

An automated blanking and forming line is designed to from 2 mm thick sheet, made from 2024 Aluminum, T4 temper, into a square sheet metal part. Elongation at 50mm 20% Young’s Modulus 70GPa Yield strength 325 MPa UTS 470 A) What is the force required to punch a square piece that is 500 mm on each edge? B) If the sheet blank was bent to a radius of 5 mm, what will be the radius after springback occurs? C) What is the required bend angle to achieve a 90° final bend angel for a bend radius of 5 mm?

Which of the following are forming operations (Please select all that apply) Extrusion Die casting Rolling Welding Powder metallurgy Drawing Continuous casting Forging

Match patterns representing different materials are allowable and specified by drawing standards. True? A. Yes B. No, they may be represented at the engineering discretion   Instead of using multiple sections for different features, I can cluster them under a single section using A. An offset section B. A half section C. A Multiview section D. None of the above

The Sleeve Bearing Problem A machinist had pressed a new prelubricated, porous sintered bronze bearing in an electric motor.  The rotor shaft would not fit into the searing.  Measuring the bore, the machinist discovered that it was a few thousandths of an inch undersized.  He removed it, put it in a lathe, and bored out the excess material.  The bearing was pressed in again, the motor assembled, and put into use.  A few days later the motor was back in the shop with the bearing burned out.  What had happened to this prelubricated, sintered bearing to cause the failure.
