PENGARUH GERAK MAKAN DAN KECEPATAN POTONG TERHADAP KEKASARAN PERMUKAAN BAJA HQ 705 PADA PROSES PEMBUBUTAN
Abstract: Quality products are
obtained from the good machining process. Surface roughness is either
aberrations caused by the cutting conditions of the machining process. HQ 705
is a mixture of hardened steel machining with high quality used in gear, shaft
engines, and other machined components. It so conducted experiments to analyze
the effect of feeding and cutting speed of motion of the surface roughness of
the steel HQ 705 at the turning process. To determine the surface roughness at
experiments using surface roughness tester. Experiments conducted at varying
cutting speed are 40 m / min, 60 m / min, and 80 m / min. The cutting speed is
set at spindle rotation 740 RPM, 900 RPM and 1230 RPM. Turning at motion
feeding variated 0.05 mm / r and 0.22 mm / r. Depth of feeding made of 1 mm for
any specimen. The experiment is obtained at surface roughness of motion feeding
0.05 mm / r obtained roughness value of 1.43 μm with a cutting speed of 77.28 m
/ min, at motion feeding 0.22 mm / r obtained roughness values of 4.296 μm with
cutting speed of 46.50 m / min. HQ 705 with a conventional turning obtained
roughness value is normal, at motion feeding 0.05 mm/r and depth of cut of 1
mm.
