Abstract
In this paper, the machining properties of Picea spp., compared with Castanopsis hystrix, were tested. Their properties were conducted according to the criteria ASTM D1666-87 and the test on crosscutting is referred to the method established by New Zealand Forest Research Institute. The results show as follow: The machining properties of Picea spp. and Castanopsis hystrix show excellent in the planning, sanding, boring, shaping and crosscutting, but in the mortising properties, Picea spp. which was a bit poor shows fair and Castanopsis hystrix shows good. The properties of Picea spp. were in an all-round way better than Castanopsis hystrix. In the machining performance comprehensive evaluation system for full marks 50 points, their comprehensive marks were separately 45.5 points and 44.4 points.
