以来老排人工林为研究对象,以红锥为对照试材,参照美国材料试验标准(ASTM D1666 - 87)和新西兰林业科学研究院标准,分别对其机械加工性能(刨切、砂光、钻孔、成型铣削、榫眼加工、横截)进行了全面测试.结果表明:米老排和红锥在刨切、砂光、成型、钻孔、横截5个单项的机械加工性能上均表现为优,在榫眼加工单项表现稍差,为良；米老排的综合机械加工性能全面超过红锥.在满分50分的机械加工性能综合评价体系中,米老排的得分为46.4分,红锥得分为44.4分.%In this paper, the machining properties (including planing, sanding, boring, shaping, mortising and crosscutting) of Mytilaria laosensis, compared with Castanopsis hystrix were tested. Their properties were conducted according to the criteria ASTM D1666-87 and the methods established by New Zealand Forest Research Institute. The results showed as follow: the machining properties of Mytilaria laosensis and Castanopsis hystrix in the planing, sanding, boring, shaping and crosscutting showed excellent, but the mortising properties which was a bit poor show good. The properties of Mytilaria laosensis were in an all-round way better than Castanopsis hystrix. In the machining performance comprehensive evaluation system for full marks 50 points, its comprehensive marks were separately 46.4 points and 44.4 points.
