Milling Forces

Cutting forces is one of the important physical phenomena in metal cutting process. It directly affects the surface quality of machining, tool life and cutting stability. The orthogonal experiments of cutting forces and influence factors with indexable and solid end mill were accomplished and the predictive model of milling force was established during high speed end milling 7050-T7451 aluminum alloy. The paper makes research mainly on the influence which the cutting speed, cutting depth and feed have on the cutting force. The experimental results of single factor showed that the cutting forces increase earlier and drop later with the increase of cutting speed, and the cutting speed of inflexion for 7050-T7451 is 1100m/min. As axial cutting depth, radial cutting depth and feed rate increase, the cutting force grows in different degree. The cutting force is particularly sensitive to axial cutting depth and slightly to the radial cutting depth.

A novel recovery process of the effective ingredient from the waste metal cutting fluid was proposed by the combination of solvent extraction and solid adsorption technique. The influence factors such as the volume fraction of 1-butanol, the ratio of solvent to oil, the quantities of KOH and the extraction temperature were studied through experiments. The results show that: The maximum quality of oil sludge was obtained when added 3g KOH to waste liquid(200ml).The mass of oil sludge was found to increase with the increase of solvent to oil ratio until it reached the maximum at the ratio of 3:1.
