Abstract: An intelligent seed production apparatus and method based on multistage screening and bud eye identification includes a feeding module, a pre-cutting module, a bud eye identifying and cutting module, and a material mixing module. The feeding module can screen out seed potatoes with the mass and shapes meeting the requirements through a multistage screening mechanism. The pre-cutting module can receive the seed potatoes discharged from the feeding module, and cut each seed potato in half; the bud eye identifying and cutting module can receive the seed potato pieces discharged from the pre-cutting module and determine the weight of the seed potatoes and identify the bud eye distribution on the surfaces of the seed potatoes, and cut the seed potato into multiple required tubers, so that bud eyes are distributed on different tubers uniformly. The material mixing module can receive the cut tubers, and complete the material mixing of the tubers.

Abstract: The disclosure provides a milling system and method under different lubrication conditions. The system uses a tool to mill the workpiece, a force measuring system to measure the milling force, a tool change system to replace the tools, a tool storage to store the tools. It can store the tools, provide the lubricating oil to the milling surface, select different tools according to different processing conditions, select the best angle differences of the unequal spiral angle tools according to different conditions comprising dry cutting, casting-type lubrication, minimal quantities of lubrication or minimal quantities of nanofluid lubrication, and/or choose the optimal tool according to different cutting parameters in order to obtain the minimum milling force.

Abstract: The disclosure provides a method and system for milling injected cutting fluid under different working conditions. By analyzing influence of airflow fields in a milling area under different working conditions on injection of cutting fluid, an influence rule of a helical angle and a rotation speed of a cutter on the flow field is quantitatively analyzed, an optimal target distance of a nozzle, an angle between the nozzle and a milling cutter feeding direction and an angle between the nozzle and the surface of a workpiece are comprehensively determined, the nozzle is set according to a determined setting manner, and lubricating oil is sprayed to the milling area by utilizing the nozzle.
