Floor kind parts has both application and very popular representative. Therefore, researching the bottom parts CNC drilling and milling process design and simulation analysis has important application value. This papers to the bottom part as research object, the comprehensive use of machinery manufacturing and the basic theoretical knowledge of nc machining, Analyzed the bottom parts CNC drilling and milling machining process, determine the bottom parts, mapped out the blank prototype of nc machining process of the bottom parts in the floor was route, design of the nc processing procedure parts, composing the bottom parts nc machining process card and process card. Using CAD/CAM nc machining module simulated and analyzed bottom parts convex platform and trough of nc machining process, established the bottom parts convex platform and trough of the nc processing model, set a floor parts of nc machining tools of planar milling machining parameters, the feeding speed, reference frame, spindle speed of processing parameters, and obtained bottom parts convex platform and trough of nc machining processing program.
