WebFor power, torque and cutting force calculations, the specific cutting force, or kc1, is used. It can be explained as the force, Fc, in the cutting direction (see picture), needed to cut a chip area of 1 mm that has a thickness of 1 mm. The kc1 value is different for the six material groups, and also varies within each group. WebThe specific cutting force (KC) ranges from 700 MPa for Aluminum up to 3,500 Mpa for nickel-based alloys. Machining a stock of Inconel will consume 400% more power than aluminum (At the same cutting conditions). Rake Angle: Every single degree of rake angle increases/decreases the power consumption by about 1%.

Specific cutting energy (SCE) and cutting horsepower (CHP) are two important concepts for efficient sawing. SCE is the amount of energy required to saw and remove wood in a certain given length of time. If a specific cutting energy is 40 hp/ft 3 /min, 40 hp is required to saw 1 foot3 of wood in 1 minute. dr graeme walker gold coast
