Abstract

The machining process design of the spindle of CA6140 lathe is the research content of this subject. For this research, a large number of data are consulted. First of all, it is understood that the machining process is to change the shape of the blank by cutting method. Dimensions and physical mechanical properties of materials become parts with required precision, roughness, etc.In order to specify the process and make the workpiece be processed in accordance with the technical requirements of the part drawing, it is necessary to formulate complex machining process rules as a guiding technical document for production. The purpose of this research is to study and study the significance and function of developing machining process rules.

The key to drawing up CA6140 lathe spindle machining process rules is the division of working procedure and the selection of positioning datum. In the beginning of the design, we must carefully analyze the parts drawing, understand the structural characteristics and related technical requirements of the box parts, and carefully analyze every detail of the box parts, such as the parallelism of the machined surface of the box, Roughness, perpendicularity, and in particular, pay attention to the accuracy of each hole system (coaxiality, roundness, roughness, etc.) and their mutual position accuracy (parallelism between axes, perpendicularity and parallelism between axes and planes, etc.), Perpendicularity, etc.), box The dimension of the part is the key to the machining of the whole part. Drawing part drawing is an important point, but also a difficult point because of the complexity of box parts. We use autoCAD software to draw part drawing, on the one hand to increase our understanding of the parts, on the other hand, to increase our familiarity with autoCAD software.
