Speed, feed, and depth of cut. 1. cutting speed is defined as the speed usually in feet per minute of a tool when it is cutting the work. 2. feed rate is defined as tools distance travelled during one spindle revolution. 3. feed rate and cutting speed determine the rate of material removal, power requirements, and surface finish. 4.
Torsional strength of the mating screw or nut. a second reliability measure is pushout. pushout values indicate the axial resistance of a fastener to remove it from the sheet opposite to the direction from which it was installed, and should be roughly 5 to 10 of the force used to install the fastener. a final test is pull-through.1 pull-through.

The screw pushes the screw backward. thus the screw rotates and moves backward at the same time. the rate at which plastic melt accumulates in front of the screw can be controlled by the screw backpressure, that is, the hydraulic pressure exerted on the screw. this also controls the melt pressure in front of the screw.
Screw compressors are categorized as intermittent motion compressors non-continuous flow. they can also be categorized with medium flow and medium pressure compressors compared with other types of compressors on pressure flow chart for compressor types. screw compressor is called so as it contains two screws, one of them is driver mounted with prime mover motor, turbine and the.
