List of process parameters in machining
What is meant by process parameters? Three process parameters in conventional machining are (i) cutting speed (N) or cutting velocity (Vc), (ii) feed rate (s) and (iii) depth of cut (t). Features of cutting parameters and difference from influencing parameters are also discussed here. Read details…
Cutting speed and cutting velocity – their relationship
Concepts of cutting speed and cutting velocity in machining, their relationship, differences and conversion of one from another using simple mathematical formula are discussed here. Classification of machining processes into rotating type and reciprocating type are also covered here. Read details…
Difference between cutting speed and cutting velocity
Cutting speed is basically the rotational speed of either workpiece or cutting tool (based on the operation). It is measured by the unit—revolution per minute (rpm). Cutting velocity is the tangential velocity of either rotating workpiece or rotating cutting tool. It is measured by the unit—meters per minute (m/min). Read detail…
Effects of cutting velocity on machining performance
Effects of cutting speed or cutting velocity on built-up edge (BUE) formation, type of chip, restricted cutting effect (RCE), cutting force, power consumption, vibration, deflection, cutting temperature, MRR, surface finish or roughness, tool life, cutting time and machining economics are discussed here.

What is feed rate in machining? Its unit, value, effects and selection
What is feed rate in machining? The auxiliary cutting motion is provided by the feed rate or feed velocity. Units of feed rate, value of feed rate for different machining processes, effects of feed on machining, formula for feed rate calculation and selection of feed value are elaborated here.
