To improve load carrying capacity and noise behavior, casehardened gears usually are hard finished. One possible process forthe hard finishing of gears is the continuous generating geargrinding, which has replaced other grinding processes in batchproduction of small to medium sized gears due to its high processefficiency. Despite the wide industrial application of this processonly a few published scientific analyses exist. The science-basedanalysis of generating gear grinding needs a high amount of timeand effort. This is due to the complex contact conditions betweentool and gear flank, which change continuously during the grindingprocess. These complicate the application of the existing knowledgeof other grinding processes onto the generating gear grinding. Thecomplex contact conditions lead to high process dynamics which posechallenges in the design of machine tools, the control engineeringand the process design. Furthermore, unfavorable contact conditionscan lead to process related profile form deviation. So theknowledge of the cutting forces and their time dependent behavioris necessary to describe and optimize the process dynamics andresults. The aim of this report is to determine the existingcutting forces for a sample gear in trials for the first time andto analyze their connection to the process parameters and theappearance of profile form deviations. Simultaneously for thesample gear the same process design will be analyzed using amanufacturing simulation. The results of the trials and thesimulation will be compared. The report will present newpossibilities in process analysis and will give the process userideas for future process improvements.
