本文主要是用CAD对拉刀进行设计。首先选择分层式拉刀，再选择出容屑槽的形状和种类，其中容屑系数K与被拉削的材料和切削厚度有关。不同的材料和厚度会造成K值的不同。接着输入数据，用公式计算出切削余量。保证加工表面达到规定的尺寸精度和表面质量、拉刀有高的耐用度和寿命和拉刀的高生产率。再对拉刀分屑槽进行设计，分别用公式计算出分屑槽宽、分屑槽的个数。然后就是拉刀的校核模块，计算出同时工作齿数，拉刀同时工作齿数最好介于3-7之间保证同时工作齿数在3-8齿以内。同时工作齿数大于8时，会使冷却润滑不充分，易使拉刀刀磨损或拉刀折断。最后校核拉刀强度和拉床拉力，当拉刀直径叫较大时，拉刀强度较大，使用时通常不用验算强度。当拉刀直径较小，使用条件改变时，应按计算公式进行强度验算。为了保证拉刀正常工作，拉刀危险断面初的应力必须小于拉刀材料的许用应力。其中计算所得到的拉削力，必须小于拉床的实际拉力。输出校核结果。通过以上结果表明使用CAD设计拉刀可以提高拉刀的质量。
Broach the structural complexity, data range, the general design method of repetitive work there, the standard low level of long-term disadvantages, such as, so to use CAD design tool of great significance for Latin America.
This article is mainly used for CAD design of the broach. First choice broach layer, and then select the shape of chip capacity and variety, in which capacity coefficient K and pulled debris cut the thickness of the material and cutting. Different materials and thickness will result in different K values. Then the input data, using formulas to calculate cutting margin. Surface to ensure the required dimensional accuracy and surface quality, high broach the durability and life expectancy and high productivity broach. And then pull a knife on chip design points, respectively, calculated using the formula crumbs Width hours, the number of sub-chip. Is to pull a knife, and then checking module, to calculate the number of teeth at the same time work, pull
