“…Not only is the efficiency and accuracy better than hobbing and shaping of the small module gears, but the spiral planetary gears without relief groove can be machined as well. Many scholars [1][2][3] in different countries have made lots of preliminary exploration on gear skiving since 1960s, such as Germany, the United States, and Japan. Nevertheless, the lag of advanced numerical control technology, precision of machine tools, and adequate tool life hindered an effective industrial application.…”

Power skiving is a modern and productive method in the manufacturing of cylindrical internal gears and external gears. However, pose errors of workpiece and cutter are caused by clamping, cutting force, and deformation of heat, which make the tooth deviation present a feature of complexity and diversity in the process of gear skiving. First, a mathematical model with workpiece and cutter pose errors is proposed to investigate the influence of sensitive error on tooth deviation by an example of internal gear skiving. Second, the correlation of tooth deviation with respect to eccentric error of workpiece, eccentric error of cutter, tilt error of cutter, and the multiple errors is studied. The sensitive errors are derived from the tooth deviation by using an orthogonal analysis with workpiece and cutter pose errors. Last, the experimental results show the validity of the numerical analysis results, and the influence of sensitive pose errors on tooth deviation can be used to identify the possible error in power skiving, as well as in gear generating method.

Tool design is one of the key factors that restrict the development of gear skiving technology since the design principle does not correspond to the cutting principle. The existing skiving tool cannot achieve ideal machining accuracy and reasonable cutting angles. In view of this, some research has been done in this paper. Firstly, the skiving principle is investigated essentially according to the skiving motions. Then, the principle of tool design is analyzed based on the theory of conjugate surface, and a new tool design method is proposed to match the skiving principle. For this, all the skiving patterns for various kinds of workpieces are enumerated and summarized to abstract a normalized skiving model. Based on this, the mathematical model of the conjugate surface is then derived to lay the foundation for tool design. Then, the design methods of cutting edge, rake face, and flank face are proposed. An example is presented at last, and the cutting simulation is conducted. The result proves that the proposed methods are correct and valid. The theoretical research in this paper could promote the improvement of skiving tools.

“…The process itself is based on a shaper-like cutting tool, which is in mesh with the gear and the cutting action is generated due to the difference in speeds between the gear and the cutting tool. Spath and Huhsam [5] presented one of the first models for the simulation of the skiving process for machining periodic structures. Klocke et al [6] presented an analysis of the power skiving process using technological and simulative approaches.…”

Power skiving is a new machining process that allows the manufacturing of external and internal gears while achieving high throughputs. Although the process was first described during the nineteenth century, it is not until lately that advances in machine tool technology allowed for the process to be implemented on an industrial scale. This paper presents a novel simulation model that enables the accurate prediction of the non-deformed chip geometry, the form and dimensions of the chips produced during the cutting process as well as the characteristics of the gear gap. The simulation model is embedded on a CAD environment in order to take advantage of their increased accuracy. Through the simulation code, the virtual simulation of the manufacturing process is realised. The simulation model was verified with the use of analytical equations regarding the form of the gear. Chip geometry and dimensions for internal and external gears machined with different conditions are also presented.
