【摘要】 在单板旋切中 ,选择最佳的定心点是旋切优化的最关键技术。本文在原木三、四点定心理论的基础上 ,提出了旋切原木六点定心理论。该理论是在原木的任意截面上取 6个点 ,由这 6个点回归出原木内包络圆柱的最佳圆心轴线 ,为高精度原木定心机的数控化提供先进的基础理论 ,提高原木的定心精度和单板的出材率及成品单板的合格率。使原木的定心理论提高到一个新的水平。更多还原

【Abstract】 For veneer peeling, the most crux technique of the peeling is how to fix the optimum centering point. In this paper based on the three points centering and four points centering theory, peeling log six points centering theory is pointed out. Arbitrarily six points of the log cross section are taken out by this theory and with these six points the optimum circle centering axis of the log internal envelope cylinder is regressed. Then the log centering precise is raised up and the veneer out put rate of end product veneer qualified rate is increased. This makes the theory of log centering up to a higher level.更多还原
