Development of 4UMS-2700 Cassava Harvester Hui Huang1, a, Zhende Cui1,b , Zhong Xue1,c , Yuan Zhang1,d 1 Agro-machinery Research Institute of Chinese Academic of Tropical Agricultural Sciences, Zhanjiang, Guangdong, 524091, China a603709530@qq.com, bcuizhende@126.com, c xxyyxz006@163.com, dzhang198414@126.com Keywords: Cassava harvester,Overall structure,Working principle,Performance test Abstract.
Introduction Cassava is one of the seven major crops with an annual output of over one hundred million tons, is the main source of heat energy among the daily foods in many tropical and subtropical regions and countries, and is also one of the most important materials which can bring us renewable energy.
In order to extend both penetrating teeth’s and cutters’ wear-resistance and life, their edges are welded with tungsten carbide – a kind of wear-resistant material.

Table 1 Parameters of experiments Speed of cutting movement 30m/min Speed of feed movement 0.06mm/r Material of abrasive Diamond Polishing tool Wool pad Conclusions When CNC machine tools polish the aspheric surfaces with a feed movement system of and θ, the displacement errors from centering operations and 3-coordinate interpolation operations make the programming trajectory of feed movement different from the required one, and it results in pose error.
