ANALISA PENGARUH PENGAMPLASAN PADA KAYU TEMBESU (FAGRAEA FRAGRANS ROXB) MENGGUNAKAN METODOLOGI PERMUKAAN RESPON
Daftar Isi:
- Tembesu (Fagraea fragrans Roxb) is one of local plant species which are found in South Sumatera. The aim of this study is to analyze the influence of one of machining process in this case sanding the Tembesu wood using the Response Surface Methodology. The study is limited to the effect of feed rate and grit size to obtain the roughness value of Ra, Rq, and Rk by using CCD (Central Composite Design) with 13 runs and additional 5 replicate runs at the center. The sanding process was done using a modified horizontal milling machine that has been given a motor on it. Experimental results are statistically analyzed by using Response Surface Methodology and Design Expert 9.0 software. It is found that feed rate had a positive effect on roughness value of Ra, Rq dan Rk. The greater feed rate will increase the surface roughness and made the surface rougher. While the influence of grit size showed a negative effect. So the larger grit size is used, the value of surface roughness will be smoother.
