Analysis of the use rate of equal arc-shaped bamboo splits

Natural arc-shaped bamboo laminated lumber (ABLL) is a new engineering material. It maintains the natural structure of the bamboo material and is of great significance in the industrial use of bamboo. We determined the material use rate of arc-shaped bamboo splits in the manufacturing process. A computer-aided design was used to establish the mathematical models among the outer radius R of the bamboo tubes and the inner radius r, the number of divisions (2 alpha/360 degrees), the radius R0 of the milling tool, and the use rate CYRILLIC CAPITAL LETTER EF. We used the Mathlab software to establish function images to analyze the influences of R0, R, r, and alpha on the bamboo use rate. Based on our results, when r < R0 < R, the material use rate is highest. The more splits, the higher the bamboo use rate. The establishment of the mathematical model optimizes the use rate of arc-shaped bamboo splits in the processing, which is of great significance for the efficient and high-quality processing of ABLL.
