  cutter
Cutting force model for a small-diameter helical milling cutter
      
In the milling process, the major flank wear land area (two-dimensional measurement for the wear) of a small-diameter milling cutter, as wear standard, can reflect actual changes of the wear land of the cutter.
      
By analyzing the wearing characteristics of the cutter, a cutting force model based on the major flank wear land area is established.
      
The cutting force model for the helical milling cutter is validated by experiments.
      
Thus, the cutting force model established in the research can provide a theoretical foundation for monitoring the condition of a milling process that uses a small-diameter helical milling cutter.

When we design or manufacture a cam more accurately, the ana-lytical method of calculation is desired. For example, by fabricationa cam the coordinate of pitch curve or centure of cutter must be de-termined; by calculation for strength and wear, the radius of curvatureof the pith curv sould be investigated. This problem has been solvedby different method, wich may be found in some literares. In thispaper the author suggest a way to establisb the systematic fotmulaswith parameters α and β.

When we design or manufacture a cam more accurately, the ana-lytical method of calculation is desired. For example, by fabricationa cam the coordinate of pitch curve or centure of cutter must be de-termined; by calculation for strength and wear, the radius of curvatureof the pith curv sould be investigated. This problem has been solvedby different method, wich may be found in some literares. In thispaper the author suggest a way to establisb the systematic fotmulaswith parameters α and β. (α is pressure angle, and β is the anglebetween radius R and normal to pith curve). For conveience to calcu-lation, several nomograms are discussed. The construction procedureof a cam is as follows: (a) Select the type of follower motion. (b)According to maximal pressure angle and nomogram 4 or 5 determinethe minimum cam size.(c) Calculate the coordinates of pitch curve byformulas(1)(2)(3)or (8)(9). If the size of roller is different from thecutter, the calculation must be continued with the formulas (6′)(7′).(d) If considering with Strength、wear or radius of roller the, radiusof curvature of the pitch curve must be calculated with formula(13).Because the method of deriving formula of the cam for oscillatingfollower or translating follower is same. so the formula for oscillatingfollower is described in detaill only.

在精确制造或设计凸轮时,都要求用分析法。例如加工时需要知道凸轮轮廓坐标或刀具的中心坐标;强度计算或磨损计算时需要知道凸轮轮廓的曲率半径等。解决这个问题有些文献已经提出一些不同的方法。这里所提出的就是以凸轮压力角α和升角β为参数,推导系统设计公式的方法。为了计算方便还讨论了几根计算图线的设计问题。凸轮的设计步骤如下:(a)选定从动件的运动规律。(b)按最大压力角和图线(4)或(5)决定凸轮最小尺寸。(c)用公式(1)(2)(3)或(8)(9)计算凸轮理论轮廓坐标。如果滚子尺寸和刀具尺寸不同,还需用公式(6′)和(7′)继续计算。(d)如果需要考虑强度磨损或滚子半径用公式(13)计算凸轮轮廓的曲率半径。因为摆动从动件和移动从动件的凸轮在公式推导的方法上是一样的,所以仅对摆动从动件的凸轮公式推导作了详细的叙述。

Computer programs capable of showing the involute form of teeth generated by interactive graphics are given. The instantaneous positions of the basic rack cutter can be displayed dynamically during "tooth cutting" with different shapes of tooth generated seen by changing the cutter geometry. This is very useful for investigations of gear parameters, its dangerous cross-sections and tooth cutting.

There are different forms of worm thread,such as Archimedes worm,involute helicoid worm,chased helicoid worm and milled worm etc.The shorter service life of worm gearing under observation in several factories has been mainly caused by the incorrect meshing of worm and gear,more specifically,the form of worm thread usually does not match the tooth profile of gear more or less.As to the analyses of the forms of worm thread on axial section in some influential texts as[1],[2],and[3] listed in reference are either...

There are different forms of worm thread,such as Archimedes worm,involute helicoid worm,chased helicoid worm and milled worm etc.The shorter service life of worm gearing under observation in several factories has been mainly caused by the incorrect meshing of worm and gear,more specifically,the form of worm thread usually does not match the tooth profile of gear more or less.As to the analyses of the forms of worm thread on axial section in some influential texts as[1],[2],and[3] listed in reference are either incorrect or calculating with trivial details even something with mistakes in conclution.This paper offers a method to form the surface of worm thread by means of a spiral motion of the contact line on worm relate to a cutter.Hence the thread surface,the form of worm thread on axial section and the pressure angle a0 on pitch circle etc may be determined or calculated by some general formulae (cf,formulae [15],[16] and [17] respectively),These formulae,closely combined with the forming process in practice,are derived more simply and more convenient for computer calculation in comparison with that of above texts.Analysis with the comparison among various forms of worm thread on axial section has been made,it indicates that a mutual repla-ceability between two worm threads is presented by their similarity as the lead angle of worm thread is smaller.It offers a choice of worm thread in consideration.The study will probably give a reference to the design of worm or worm hob.Nomenclature: X2,y2 and z2——coordinates of worm thread surface;x1,y1 and z1——coordinates of contact line on worm relate to a cutter in spiralmotion;x0——variable of contact line on worm relate to a cutter in spiralmotion;p——parameter of spiral motion;θ——revolving angle of spiral motion;γf——radius of reference circle of worm;αa——axial pressure angle of worm;α0----tool angle;Δ——lead angle of worm;αn——normal pressure angle of worm;s0——thickness of tool at rf;w0——thickness of worm thread at rf;
