The hydro chuck spindle enables an accurate and quick cutting tool change. The WTO Power Skiving Unit offers high stiffness and runout accuracy. The great advantage of this method is the use of a tool that is not geometrically related to the shape of the machined gear profile, which allows the production of cylindrical gears with a tooth and profile line other than the standard. Highly productive gear machining: Skiving of ID and OD splines on CNC Turning Centers. The presented method is able to provide a very good quality of machined gears in relation to competing methods. The side surfaces of the teeth after machining according to the planned strategy were also assessed the tests were carried out using the optical microscope Alicona Infinite Focus G5 and the contact profilographometer Taylor Hobson, Talysurf 120. The conformity of the outline, the tooth line, and the gear pitch were assessed. It is not a new concept, with the initial solution being patented in 1910 in G.
POWER SKIVING DMG PRO
The manufactured gears were inspected on a ZEISS coordinate measuring machine, using the software Gear Pro Involute. In recent years, gear skiving, also known as power skiving, has been drawing increased attention as a productive and precise cutting method, especially for internal gears.
Made of steel 16MnCr5, gear wheels with a straight tooth line and with a longitudinally modified convex-convex tooth line were machined on a five-axis CNC milling machine DMG MORI CMX50U, using solid carbide milling cutters (cylindrical and ball end) for processing.
POWER SKIVING DMG CODE
On the basis of the presented mathematical model, a software was developed to generate a code that controls a machine tool for machining cylindrical gears with straight and modified tooth line using the multipass method. The most common standard for cylindrical gear classification is DIN.
Gears are normally classified according to a standard specifying tolerance requirements for the gear wheel after the machining operation. Today, special attention is paid to the technology of making gears using universal CNC (computer numerical control) machine tools with standard cheap tools. Power skiving will be in focus since it will replace shaping, broaching and spline rolling, along with hobbing to some extent. Study of Machining of Gears with Regular and Modified Outline Using CNC Machine Tools Materials ( IF 3.057), Pub Date : , DOI: 10.3390/ma14112913 Rafał Gołębski, Piotr Boral Classic methods of machining cylindrical gears, such as hobbing or circumferential chiseling, require the use of expensive special machine tools and dedicated tools, which makes production unprofitable, especially in small and medium series.
