Innovative Technologies in Machine Building I International Scientific and Practical Conference « Actual Problems in Machine Building » ________________________________________________________________ 82 Treatment with rational cutting force L.P. Kolot, S.G. Onishchuk The paper considers the methods of forecasting and anticipation of the errors of the form of surfaces of details of type of table milling machines, frames open-type racks. Errors due to redistribution of internal stresses during cutting and elastic wringing out in sections with low rigidity. Developed a method of pre-emption of the errors in the form of parts, based on the principle of inter-compensation of distortion from the redistribution of residual stresses after removal allowance and elastic wringing out under the action of the component cutting force P y , because they point in opposite directions. Dependence of influence of the initial parameters of the processed parts of the component cutting force P y expressed through cutting modes. The variable value is the value of the horizontal feeder's, with the help of which the control of the error of the form. Key words : error of the form, internal tension, stiffness, allowance, cutting force
