Derive cutting forces

WebAccording to our working hypothesis, the four types of forces acting in the saw-teeth during timber processing are (1) the sawing or cutting force Fs, (2) the saw dust acceleration force Fa, (3) the saw dust compacting force in the gullets Fc, and (4) the force needed to overcome the increasing friction from wear Fw. WebSep 2, 2024 · As a simple starting example, consider a beam clamped (\cantilevered") at one end and subjected to a load \(P\) at the free end as shown in Figure 2. A free body diagram of a section cut transversely at position \(x\) shows that a shear force \(V\) and a moment \(M\) must exist on the cut section to maintain equilibrium.
