Study on Machining Quality of Knotter Frame of Square Baler

Aiming at the knotter frame's feature of complicated structure, poor rigidity, high precision, inconvenience of fixture, easy to deform, difficult to ensure the machining quality. This paper makes preliminary research from three aspects of the frame machining process scheme, cutting parameters selection and the machining surface quality. Doing orthogonal test and processing related data, which about the cutting force, temperature field and stress field, coming from cutting simulation software AdvantEdg about cutting machining simulation by using the range analysis method, and then getting the basic rules of cutting machining affected by the cutting parameters, finally getting the optimal combination of cutting parameters of each process. This provides reference for the selection of the frame machining process scheme and the selection of cutting parameters of each process.
