| description | Planing is one part of the machining properties. It's refers to the peripheral milling of wood to smooth one or more surfaces of the work piece and at time bring the work piece to some predetermined dimension in thickness, width or profile pattern. Normally this operation is carried out with the grain direction and feed direction arranged in such a way that the knives cut parallel to the grain in up - milling orientation. Objective of the study are; to compare the planing properties and 2 ages of Sentang, to determine the planing character geometry on Sentang and to study the effect of various defects such as Chipped grain, Fuzzy grain and Woolly grain are influent on finishing. In this study the material used are 8 and 40 years old of Sentang (Azadirachta excelsa) which is a Light Hardwoods derived from family of Meliacaea. 8 years old samples come from Felda Kampung Kerayong, Kuala Selangor and 40 years old samples came from FRIM Plantations (Bukit Lagong Forest Reserve Selangor). This study is regarding to the moisture content, density, cutting angle, pitch of knife marks, depth of cut and age of samples. Planing test was determined by using the Six heads high speed moulding machine. The results was determined by observation which is used the suitable apparatus. ANOYA (Analysis of variance procedure) are the statistical method to analyze on planing test results. From the results and discussions, show that 40 years old samples had a highest ratio of Chipped, fuzzy and woolly grain defects compared to 8 years old samples. The ratio of chipped grain defects was only reduced when the cutting angle and pitch of knife marks were reduced. The ratio of fuzzy defect more prone on the test samples compared to another two types of machining defects. Sample condition is also influent the results, where the 40 years old samples had more knots, pin holes and the fraction of the work piece. To ensure that results more practical a few recommedation. |
