EFFECT OF LONGITUDINAL FEEDS ON FLAT GRINDING PROCESSES ON VIBRATION AND SURFACE ROUGHNESS IN OCR12VM MATERIAL

The grinding process is machining to achieve a high-quality surface finish and high dimensional accuracy. There are two primary processes, the roughing finishing process. generates higher dynamic cutting forces than It leads vibration that reduces ground quality, tends lower accuracy, shortens wheel life. On other hand, applied reduce time, increasing productivity. We conducted this research study effect of longitudinal feed on roughness hardened tool steel OCR12VM (equivalent JIS SKD 11), machined by was varied from 100 mm/s up 250 with 50 increment. Each variation depth cut 0.01 mm, 0.02 mm 0.03 respectively. constant parameter set: n= 3000 rpm, transversal feeding= 0.04 mm/stroke. dimension grit 80 Aluminium oxide wheel= Ø 200 x 25 mm. result showed linearly proportional RMS level. effects increased resulted roughness. data trend line has square function feed. similarity, as previously mentioned, vibrations level also increases quadratically Thus, it evident closely related during Based result, can predict measuring without
