EN The results of studies of cutting forces and power are presented when turning AlCu4MgSi alloy under various cooling conditions and using various coatings on inserts. It has been found that the conditions for cooling the cutting zone affect insignificantly the cutting forces with a certain decrease for the case of MQCL. The effect of the coating composition is also small, except for the case of cutting with a larger cutting depth and lower feed rates and cutting speeds, when TiAlN coating provided a reduction in the cutting force by 1.7–2.5 times. The relationship between the components of the cutting force can be described by the dependence Fc ≈ Fp > Ff. The intensity of the influence of the cutting parameters on the forces decreases in the direction f → ap → vc. The cutting power is low, less than 2 kW. The exception is cutting with maximum speed and significant feeds and cutting depths, which can be explained in this case by the influence of the inertia force.
