Abstract	The machining of cylindrical gears by gear shaping with gear wheel-cutter has accompanied of known cutting errors met at rolling gears cutting: pitch error, total pitch error, profile tooth error, circular runout, etc. The technical papers consider that two aspects can analyze gears shaping precision with gear wheel-cutter: first by the analysis of profile gear cutting errors, and second by profile gear cutting errors in “closing zone of teeth gear”, with a main factor according of stiffness machine tools. The analysis of stiffness machine has done with the values displacements and relative rotations of machine subassemblies to a fixed datum system and two mobile datum systems, in dependence of load applied during idle running or gear shaping process, could be defined three stiffness’s: static, quasi-static and dynamic stiffness. During the cutting process, the variation predictable distance between cutter axe and wheel-workpiece axe is important. This study is carrying out by stiffness machine analysis in radial direction of OY axe. The paper has proposed a method of quasi-static stiffness machine determination of gear shaping process with wheel-cutter. During cutting process occurs altering positions between subassemblies of ram-toolholder and rotated table, even is used finishing working conditions. The research has done by an integration system “force-displacement”, formed by a dynamometer adaptable of gear machine-MD 250, which allowing the acquisition of cutting forces on three axes and displacements of ram-toolholder-workpiece during machining process. The measurement has done in “closing zone of gear”, respectively the outside of that, due to determination of stiffness machine tools. In addition, this research presented the assessing of working accuracy of gear shaping machine with gear wheel-cutter.
