Problems solved by technology

[0004] From the above research results, it can be seen that many scholars have carried out the research on the grinding method of the end tooth flank of the integral end mill, but there are relatively few studies on the interference and other problems that often occur in the actual machining process, and most of them use the grinding wheel for grinding. Grinding, the grinding quality is not high

Embodiment Construction

[0087] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. The method for solving the grinding track of the end tooth straight grain type flank of the integral flat end mill of the present invention, the specific steps are as follows:

[0088] Step 1: Definition of relevant geometric parameters of end tooth straight edge

[0089] The definition of the straight-grain flank structure of the end tooth of the integral flat end mill and the algorithm of the grinding trajectory of the end tooth flank are based on the precise description of the geometric characteristics of the straight edge of the end tooth, such as figure 1 shown. The relevant geometric parameters of the straight edge of the end tooth are defined as follows:

[0090] (1) Blade length L t

[0091] Define the length of the helical edge of the peripheral tooth along the direction of the center axis of tool rotation as the blade leng...

Abstract

The invention discloses a method for solving a grinding track of an end tooth straight grain type flank surface of an integral flat-end end mill. The method comprises the following steps of: establishing the end tooth edge line of the integral flat-end end mill with tooth pass and tooth offset structural characteristics, and proposing an edge grinding model for the end tooth straight grain type flank surface. According to the model, the end face of the grinding wheel serves as a grinding face, the grinding quality can be guaranteed, the flexibility of grinding posture definition of the grinding wheel is achieved by adjusting technological parameters such as the swing angle and the lifting angle of the grinding wheel, and blade grinding interference is avoided.

Description

technical field [0001] The invention relates to the technical field of high-precision grinding and manufacturing, in particular to a method for solving the grinding track of an end tooth straight-grained flank of an integral flat-end end mill. Background technique [0002] The solid end mill has become one of the main processing tools for milling because of its good cutting performance and geometric versatility. At present, the research on the manufacturing of integral end mill sharpening has attracted the interest of many researchers at home and abroad [Li Guochao, Sun Jie. Research status and development trend of integral end mill sharpening simulation technology [J]. Chinese Journal of Mechanical Engineering, 2015 ,51(9):165-175. (LI Guochao, Sun Jie.Current Research and Development Trends of End Mill Grinding Simulation Technology[J].Journal of Mechanical Engineering,2015,51(9):165-175.)]. However, with the increasing complexity and accuracy requirements of the structur...
