Forming and Shaping

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the shearing and machining process, the material does not undergo up to a failure point as indicated in the stress-strain curve. Hence, the stresses induced during the forming process are greater than yield strength but less than the failure strength of the material. The process does not lead to the loss of material, so it can be said to be an economical process. During forming, the material is subjected to tensile forces, compressive forces, bending, and shearing loading conditions. The material should possess the property of ductility to undergo the forming process.

Problem 4: Inputs: a = 4.5" (the "symbol indicates inches) b= 1/4" (rod diameter) ● F₁ = 13 lb ● Have you ever wondered how bolts get their threads? Well, we start with a smooth rod and then cut the threads into it. The thing that cuts the threads is called a "die." Although machines can be used for this process, it is often done by hand as well, and that's what we're looking at on the right. F₁ Handles a Die The "die" is in there a F₁ bk F₂ Threads Rod So suppose you want to cut threads on this rod. You would get the correct size die (they come in lots of different sizes), and place it inside the handle. Then you would twist the handles around the rod, thereby cutting the threads with each revolution. For this problem, suppose you apply a force of F₁ to the handles. What is the force F₂ exerted on the rod? Use couples for your solution. F₁

Pneumatics Bending Tool Problem: Sheet metal is to be bended on a pneumatically actuated bending rig. After it has been clamped the piece is initially bent by a double-acting cylinder A and subsequently bent into the finished form by cylinder B. The sequence is initiated manually by a push button. The circuit must be so constructed that each time a start signal is given a full cycle is completed. Positional Sketch: 1.0 2,0 Electro-pneumatics Sequential Circuit Problem: Initial position all cylinder are retracted. Pressing the start pushbutton makes 5 cycles. After making 5 cycles lamp is energized for 3 secs. Cycle Operation: Cylinder A extend and hold the work piece. Cylinder B extend for 5 secs. Then retract. Cylinder A retract.
A CNC worktable is driven in a linear direction by a lead screw connected directly to a stepper motor. The pitch of the lead screw is 5 mm. The stepper motor completes one full revolution upon receiving 600 pulses. If the worktable speed is 5 m/minute and there is no missed pulse, then the pulse rate being received by the stepper motor is (a) 20 kHz (b) 10 kHz (c) 3 kHz (d) 15 kHz

- An end milling operation is carried out along a straight line path that is L=325 mm long. The cut is in a direction parallel to the x-axis on an NC machining center. Cutting speed = 30 m/min and chip load = 0.06 mm. The end milling cutter has two teeth and its diameter = 16 mm. The x-axis uses a DC servomotor connected directly to a leadscrew whose pitch = 6 mm/rev. The feedback sensing device is an optical encoder that emits 400 pulse/rev. Determine (a) feed rate and time to complete the cut along the path L, and (b) rotational speed of the motor and the pulse rate of the encoder at the feed rate indicated.
