Computer simulation of dynamic processes in power skiving gear cutting

The paper presents the results of simulation of the dynamic processes during gear cutting using the power skiving method.  Oscillations in the elastic system of the machine tool have been studied using the Simulink Matlab system.  The closed dynamic system is represented as a series-coupled connection of the elastic system of the cutting process and the elastic system of the machine tool, which is assumed to be two-mass, with masses applied to the table assembly with the workpiece and to the tool spindle.  The input signals of the cutting process system – the thickness

INFLUENCE OF AXIAL TOOL FEED ON UNDEFORMED CHIP GEOMETRIES IN POWER SKIVING GEAR CUTTING

The purpose of this article was to formulate recommendations for developing strategies for multi-tool cutting of gear wheels that ensure a productive and reliable process for ensuring the accuracy and quality of machined surfaces.  The determination of the effective axial feed rate to achieve maximum productivity has not yet been fully explored. The objective of this article is to ascertain and examine the impact of axial feed on the chip formation process during the cutting of the gear rim.

INFLUENCE OF PROCESS KINEMATICS AND TOOL DESIGN ON GEAR MACHINING BY POWER SKIVING

The article presents an alternative approach to the description of the cutting scheme, different from the accepted one, which corresponds to the real kinematics of the Power Skiving process. The interpretation of the process is based on the fact that the main cutting movement is the rotational movement of the tool, which, due to the intersection of the axes of the tool and the workpiece, forms the constructive movement of the face in the direction of the axial feed.

Investigation of Tool Temperature During the Cutting of Internal Gears Using the Power Skiving Method

Problem statement and the research purpose. One of the main factors determining the intensity of tool wear is the temperature that arises during the cutting process. Thus, the objective is to investigate the patterns and obtain dependencies of heat generation and heat transfer between the elements of the cutting process that characterize the temperature of the tool’s teeth and blades.

DETERMINATION OF GEOMETRIC PARAMETERS OF UNDEFORMED CHIPS AT THE STAGE OF CUT IN DURING MULTI-PASS CUTTING OF THE INTERNAL GEAR BY POWER SKIVING

The article presents the results of modeling and studying the processes of cutting internal gears by the power skiving method based on the previously developed graph-analytical model of cut layers. The results of the calculations of the geometrical parameters of undeformed chips can be used to calculate the forces that occur in the process of four-pass gear cutting and influence the parameters of this process.

Simulation of the power skiving process for cutting an internal gear with modelling of undeformed chips

Aim. The aim of this paper is to create a 3D model of the undeformed chips produced during the cutting of an internal gear ring. By modelling the power skiving process, it is necessary to investigate the influence of various geometric and technological parameters on the thickness and cut area of the chips produced. Method. By simulating the gear turning process, it is possible to reproduce the cutting of the gear teeth and accurately determine the geometric parameters and the shape of the undeformed chip at each moment.
