摘要：Modern gearboxes are characterized by high torque load demands, low running noise and compactdesign Gear assemblies, gear box and quality of its components (referring to gears) play an important role duringtransmission mechanism. Many issues have occurred and still do occur during the processing of gears especially inareas of Hobbing , Shaving, Heat Treatment processes, etc and best trials are carried out so as to attain definitesolutions to the encountered problems. Oerlikon Fairfield- a gear manufacturing MNC successfully uses Root CauseAnalysis Techniques (PDCA cycle, Cause and Effect Diagram with Shainin Technique combination), DMAIC qualityimprovement Methodology in order to solve the problems occurring during part’s processing. The present paper dealswith Sine Pattern problem occurring during processing of new development part i.e. spur gear. Sine pattern occurrenceshave to be controlled stringently as per K sheet specifications. Current problem being one of major quality issues isresolved and controlled by using a combination of Cause and Effect Diagram with Shainin Technique and DMAIC-6sigma break through methodology. Tool modifications being tried as final resort and hence implementation ofmodified shaving cutter during shaving stage helped in achieving the corrected sine pattern profile within the requiredK sheet specifications.
