辽宁省丹东木材公司积极推广应用优选法,取得了一定效果。一、优选法在42吋带锯机上的应用丹东木材公司木制品车间42吋带锯机,多年来,一道锯上锯45分钟到1小时就须换锯,锯条常常裂口、裂纹,即浪费锯条又危险,影响产品质量和效率。通过各方面的分析,从解决锯齿几何角度,提高使用效率入手,采用单因素方法进行优选试验。优选范围确定58-70°,经过三次优选,获得了最佳点。第一点:(70-58)×0.618+58=65.416°(取65°) 第二点:(70+58)-65=63°
Dandong Timber Company of Liaoning Province has actively promoted and applied the optimization method and achieved certain results. First, the preferred method in the 42-inch band saw machine application Dandong wood company wood products workshop 42-inch band sawing machine, over the years, a saw sawing 45 minutes to 1 hour to be sawing, sawing often cracks, cracks, that is, Dangerous, affecting product quality and efficiency. Through various aspects of analysis, from the perspective of solving the geometric sawtooth, improve the use efficiency, the use of single-factor method for the preferred test. The preferred range is 58-70 °, with the best of three passes. First point: (70-58) × 0.618 + 58 = 65.416 ° (take 65 °) Second point: (70 + 58) -65 = 63 °
