Abstract The influences of spindle speed, feed rate and radial cutting width on cutting forces were analyzed during the orthogonal plunge milling experiment of aluminum alloy. Analysis of variance was carried out and multiple linear regression equations of the cutting parameters were established at the same time. The influences of machining chatter on the signal of cutting forces were discussed. The relationships of cutting forces, tool engage angle and instantaneous chip thickness were analyzed which contributes to dividing the cutting zone into squeezing area, scratching area and cutting area.
