Important Results on External Cylindrical Plunge Grinding with Unusual Workpiece Peripheral Speeds and Speed Ratios q in the Range of -0.2 to -20 000

摘要: The speed ratio q is defined as quotient of cutting v c and workpiece peripheral ft at the principle point D. may be negative or positive (up-grinding down-grinding). grinding process influenced by ratio. traces single grains are nearly circular for high ratios can extremely cycloidic low ratios. Speed between 50 100 normally used most external plunge operations. Important characteristic quantities like roughness, forces, temperature wheel wear presented functions For first time was varied 0,2 20000. metal removal rate were constant. investigations made with aluminium oxide wheels a CBN-wheel in creep feed grinding.
