Explain why continuous chips are not necessarily desirable.

Expert Solution & Answer

To determine

Explain why continuous chips are not necessarily desirable.

Explanation of Solution

In computer-controlled machine tools, continuous chips are not preferred. This is because they can get tangled around the tool holder, fixture or even the workpiece. It can also get tangled into the chip disposal system. To clear these chips, it is possible that the operation may be needed to halted.

This problem can be resolved if we use chip breakers. The cutting speed can be changed, or the feed, depth of cut can be varied. It can also be solved by using cutting fluids.

Q Derive (continuity equation)? I want to derive clear mathematics.

motor supplies 200 kW at 6 Hz to flange A of the shaft shown in Figure. Gear B transfers 125 W of power to operating machinery in the factory, and the remaining power in the shaft is mansferred by gear D. Shafts (1) and (2) are solid aluminum (G = 28 GPa) shafts that have the same diameter and an allowable shear stress of t= 40 MPa. Shaft (3) is a solid steel (G = 80 GPa) shaft with an allowable shear stress of t = 55 MPa. Determine: a) the minimum permissible diameter for aluminum shafts (1) and (2) b) the minimum permissible diameter for steel shaft (3). c) the rotation angle of gear D with respect to flange A if the shafts have the minimum permissible diameters as determined in (a) and (b).
