ABSTRACT: Tests are reported designed to determine experimentally the best de-phasing angles of the separate'milling cutters in a gang milling set-up so as to reduce the cutting torque fluctua- tion to a minimum. Careful tool grinding reduced the cutter eccentricity in these tests below 0.03 mm. engineering steel (0.39o' C) with a tensile strength of 48 kg/mm and grey cast iron with a Brinell hardness of 130 were machined on a horizontal milling machine at d8pths of cut of 2-10 mm (corresponding to contact arcs of 10-45 and a range of advances per tooth between 0-05 and 0.2smm. Most tests were carried out at cutting speeds of 15-40 m/min apart from one series of high-speed tests run at 150 m/min. No coolant was used. Strain gauges bonded to the cutter mandrel transmitted the cutting torque through a carrier wave system. The tests included gangs consisting of cylindrical, face, angle and form cutters. The relative angular positions were shown to cause large differences in tool life. Cardl/2 An analysis is given followinE the realisation that fluctuations 122-2-15/33 The Determination of the optimum Angular Shift of Milling Cutters in Gang Milling in the instantaneous cross-section engaged by the gang are the main reason for uneven cutting torque. The geomtrical analysis includes the cases of form cutting by angle and radius cutters, the milling of slots with disc cutters having straight or helical teeth, surf-ace milling with cylindrical cutters and the General case of arbitrary shape cutters. The improvement in the work of the milling machine is expressed by the improved utilisation of the power installed and by an increased efficiency (from 65 to ?5%). There are 5 figures, 1 table and 3 Russian references.

A graph (rigure 2) shows the experimentally determined stiffness cbefficient as a function of the cutting force. The wobble of the cuttcr and its mandrel were tested under load. The initial wobble of 0.03 mm increased under load to 0.06 mm. By reducing the iength of the mandrel and by appropriate pre-loading of the cutter spindle roller bearings, the error of the axial dimensions could be reduced from 0.05 to 0.02 mm. In gang milling, the optimum relative phasing of the cutter teeth can substantially reduce the total cutting force (author's paper in this journal, 1958, Nr 2). The tests have shown Cardl/2 that the misalignment of the table feed motion yields the SOV/122-59-6-17/27 On the Accuracy of Milling with Disc Cutters greatest errors In the milling of deep slots.

The divergence of the results of measurement and-the deviation from the theoretically calculated values is reduced to the fact that the light was not completely monochromatic.
