提高出材率的主要技术措施有下面几点:1.实行锯口设计。即以梢径为准,根据锯材要求,考虑钝稜允许范围,按径设计锯口。2.合理断配。根据各种不同类型的原木,采取不同的断配方法:凡弯曲原木和毛板,都应采取“先截断,后锯板”的方法,以增加材积;但对于毛板制箱或制短料时,应采取“先锯板后截断”的办法以掌握合理取材。3.合理利用钝稜。根据不同加工构件和用途,在不影响使用条件下结合原木天然的缺点程度,可锯制部分带钝稜的成材。
Improve the material rate of the main technical measures have the following points: 1. The implementation of kerf design. That is, whichever is the tip diameter, according to the requirements of lumber, consider the allowable range of the obtuse edge, according to the diameter design kerf. 2. Reasonable with the allocation. According to different types of logs, take a different method of allocation: Where bent logs and hair board, should be taken “first cut off, after the sawing board ” method to increase the volume; but for the hair board box or system Short material, it should be taken “first saw after the cut off ” approach to grasp the reasonable material. Reasonable use of blunt edges. According to the different processing components and purposes, without affecting the conditions of use combined with the natural degree of defects of the wood, sawing some of the products with blunt edges.
