a) A workpiece (φ-75 mm, 1 275 mm) is machined using turning at a feed rate of 0.25 mm/rev. At a cutting speed- 3.5 m/s, the turning tool is ineffective after machining 3 parts, and at a cutting speed = 2.5 m/s, the turning tool is effective for producing 20 parts. Calculate the Cutting Speed that will allow 30 parts to be machined between tool changes [20 marks] b) An aluminium alloy workpiece (tensile strength - 325 N/mm2 and yield...

A face-milling operation is being carried out on a 320-mm-long, 110-mm-wide, 50-mm thick annealed mild- steel block. The cutter follows a path that is centred over the workpiece and is applied on the top surface where it reduces the part thickness into 44mm. It has four teeth and is 150 mm in diameter. Cutting speed = 132 m/min, and chip load = 0.23 mm/tooth. Determine: Maximum metal removal rate during milling metal removal rate = _______________ ( ) Machining time...

A slab-milling operation is carried out on a 200 mm long, 80-mm-wide annealed mild-steel workpiece having a feedrate of 0.1 mm/tooth and a depth of cut of 4.0 mm. The cutter of 50 mm diameter has 18 straight teeth and rotates at 135 rpm. The given specific energy for this material is 3.5 W s/mm3 and the slab mill is wider than the workpiece to be machined. Calculate: ‧ the material-removal rate; ‧ the power and torque required for this...

Problem Statement You are the manager of a workshop. You need to turn 1,500 shafts as an intermediate step in a larger manufacturing process. It takes your workshop technician 20 min to machine a single shaft at a cutting speed of 15 m/min and 10 min to set up the blank in the spindle. Since you are turning 1,500 shafts, the technician will certainly change the cutting tool to maintain quality - a tool change would require five minutes. The...
