Abstract

The rapid development of wood products led to improvement of techniques and needs for machines that used to process the wood . Wood machining is the process of shaping or cutting wood hy using a machine using including cutting tool , through single or comhination of sawing , planing, shaping ,routing , turning , sanding, etc. Because of that, the researcher used a horizontal milling machine in wood machining process to determine the effect of feeding ( mm / min ) and gril size on surface roughness of merbau . This reseach focused on the process of sanding using method of CCD ( Central composite design ) that used to varying the grit size (120 ; 180 ; 240 j and feeding (17 ; 25.5 ; 34 mm / min ) , while the depth of cut is 1.5 mm on surface roughness (Ra j of 13 specimens The measurement of Wood surface roughness was using a surface tester Accretech Handysurf E - 35 A / E by taking 3 different points on the specimen . Ra data obtained is the result of an average of 3 points measured . The results of the mar.imum and minimum roughness of Ra are 5.23 prn and 3.3 pm minimum . The conclusion that got f r om this research are Ra v.ould increase when feeding increased and decrease when grit size increase. Then the greater value of Ra at the end of the sanding. Keywords : wood machining, sanding, merbau wood, grit size, feeding, surface roughness.
