March 2014—11 characteristics needed for both productivity and extended tool life during power skiving. Machine setup, cutter handling and logistics remain as simple as in shaping. When resharpening is needed, the end user sends it out to a local resharpening source that resharpens the face, strips, recoats and returns the cutter within a few days. The profle quality remains untouched. Also note that operating in conjunction with new machines and the power skiving process, Gleason's cutting tools are designed to provide higher quality and better surface fnishes than shaping has traditionally delivered. The power skiving generating motion provides a "softer," less-abrupt chip formation that is smoother and more consistent throughout an entire cut. Profle modifcations as well as a tooth tip chamfer can be built into the cutter while lead modifcations are realized by additional movements of the machine axes. The cutting cycles can be modifed for aggressive roughing and fne fnishing to maximize both productivity and quality. Profle, lead and tooth thickness can be corrected according to the results shown on the inspection charts. Ultimately, a quality of DIN 7 or better and surface fnishes of Rz 4 μm (Ra 0.6 μm) are possible. Simulation Software Until recently, it was impossible to effectively establish the boundaries at which the skiving process exceeds its limits and won't work well. Nor was it possible to truly optimize the process in advance due to the lack of appropriate software. Anticipating chip formation and collision points was diffcult, if not impossible, to evaluate without the appropriate software. Today however, Gleason offers comprehensive Power Skiving Technology Software that enables end users to easily simulate the entire cutting process and plan the most effective process strategy. The software can analyze the infuence of different cutting tool geometries and process Gleason Power Skiving machines operate wet to enhance chip evacuation and minimize accumulation. 0314_MMS_Gear_RussFeature_EDIT.indd 11 2/13/2014 2:43:08 PM
