Basics of belt drives | Plant Engineering

Basics of belt drives. Power transmission belting has been used for more than 200 years. The first belts were flat and ran on flat pulleys. Later, cotton or hemp rope was used with V-groove pulleys to reduce belt tension. This led to the development of the vulcanized rubber V-belt in 1917. The need to eliminate speed variations led to the ...

Milling Process, Defects, Equipment - CustomPart.Net

Feed rate - The speed of the cutting tool's movement relative to the workpiece as the tool makes a cut. The feed rate is measured in inches per minute (IPM) and is the product of the cutting feed (IPR) and the spindle speed (RPM). Axial depth of cut - The depth of the tool along its axis in the workpiece as it makes a cut.

What is Feed Rate in Machining? Its Unit, Value, Effects and Selection

Feed rate in drilling—Must be very low otherwise tool may break due to chip clogging. Typical value is 0.01 - .05mm/rev. Feed rate in milling—Usually 0.05 - .10mm/rev. Feed rate in knurling—0.5 - 1.0mm/rev (Cutting speed is usually very small in knurling but feed rate is very high). Pros and cons of improper feed rate
