METHOD FOR COMBINED MACHINING CYLINDRICAL PARTS

摘要

SUMMARY OF THE INVENTION: wear on the surface of cylindrical parts cutter applied microtopography and the deforming element is produced tons its plastic deformation. When applying the microrelief to the cutting tool oscillating force applied in the direction of the axis of rotation of parts vary depth penetration and the oscillation frequency according to the magnitude of surface wear. Oscillation frequency and infeed depth of the cutting tool is varied depending on the wear according to the following ratios :. h i + Ah + (U-2l / UnpeA.) U; n n D2N / 4x x (1 1 U / U before 1). wherein -Vg (Dl H- D2} / Dl 02 (1 + 1) Ro, (D1 + D2) / Dl D2 (1 - (M1 / E1 -f 1 -fl $ / E2) P, h - alterable value infeed depth of the cutting tool; U - wear value alterable in length parts; - forestall - limiting znachenie.iznosa; i - g tension deforming member relative to the workpiece surface; n - frequency of axial oscillation of the cutting tool; Di, D2 - diameters of the deforming element and parts , / and / 42 - Poisson's ratios of the deforming element and parts; EL Ј2 - moduli of elasticity of the deforming element and details; Ah - elastically recoverable metal height;. P0 - maximum he led Ichin on the force applied to the deforming member, resulting in a phenomenon of plastic deformation; F - the force applied to the deforming element during processing; N - rotational speed detali.2 yl .. 6: 00.
