Palm Cutting Parameter Optimization of Orbital Cutting Blade Chopper Machine

Abstract

 Lower palm branch cutting technique was a productivity method in a palm growing area due to this cutting technique could store more food for the palm tree, produce a new palm branch and also affect to increase a higher palm fruit. To perform this technique, larger amount of the palm branch waste was produced and was required to utilize as a fertilizer or an animal feed in the near future. Therefore, the palm chopping that could produce small scrap size and suit to utilize was continuously performed. This article aimed 1) to experimental design for optimizing cutting parameter that could produce small scrap size and large amount of scrap using an orbital cutting blade palm chopping machine and 2) to study the laration of the cutting parameter that could influence the palm scrap size and amount. The cutting parameter in this study was composed of the cutting speed of 540-1000 rpm and cutting blade amount of 2-6 blades. 2³ factorial statistical analysis technique which was 2 factors and 3 levels, was carried out to design and analyzed the experimental results. The summarized results are as follows. The optimized cutting parameter that could produce the palm scraps size of 3.8 millimeters and the palm scrap amount of 6600 grams was a cutting speed of 1000 revolutions per minute and the cutting blade of 6 blades. An increase of the cutting speed and an increase of the blade amount affected directly to decrease the palm scraps size and increase the palm scrap production amount.
