3。钻削力模型

3.1钻削力

在过去几十年历史的建模,群众举报的钻探力量预测方法很多,其中大部分是用于标准麻花钻。由于缺乏先进的计算机和测量设备,早期研究的一个简单的扭矩和轴力的重点经验模型的建立,模型参数钻几何参数(如钻头直径)和切削参数,采用建模方法切削实验的使用武力的钻井统计方法拟合大量的经验公式。

利用钻井力模型分析成立人削减深入的逐渐形成过程的理解方法。 1955年,牛津记录微观主体演习照片横刃和芯片变形过程,并通过实验发现:钻井过程中,在三个领域,即主要地区存在演习来看,主要前沿领域,第一第二刀刃(交叉边缘)伐区和核心区附近的特征。后来,肖MC和牛津弯曲菌Jr证明凿在钻探的重要性,因为它产生了50%〜60%的轴向力。 1966年,库克信息NH提出半年与派生式钻井方法的分析方法。邵氏三菱商事(1962,1984),在芯片的变形机制,深入的芯片主要叶片模型变形位的基础研究。威廉姆斯铁(1974年)提出了单点二为基础的工具切割刀片的主切削力模型演练三维模型,并确定钻头直径描绘领域。 Armarego伊科(1972年)的斜角切削理论的应用,提出了平面钻切削力预测模型。 Wiriyacosol拧(1979年),下薄剪切带(剪切面)理论芯片变形等,将主要演练和横刃刀片切割作为一个模块在直角斜面或刀具系列组合条件通过这些模块的工具积累预测钻井切削力,即线性刀单位的合成方法。剪切停留在理论的基础上飞机,奥克斯利弯曲菌Jr(1959,1962年),Armarego伊科(1972,1979)和华生铁(1985年),分别设立了一个不同的钻井力模型集; Stepenson达(1988,1989年)提出的数学计算方法,钻探力量。钻削力

钻削力模型的研究是作为所有新钻头的钻井技术的人不断深入发展。吴钐,谁建立了切削力模型库演练了很多工作要做。其中,李西南(1986年)和复哈诺夫(1987年)的工作,无论是主要切割斜角切削模型,第二尖端成直角使用切割模型,建立了优势,切削角一个钻石切削力模型组,黄羟色胺(1992年),谁提出了预测机械麻花钻组轴向力和扭矩的方法的一般模式。 Armarego伊科和赵会(1996年)设立一个标准麻花钻钻芯薄,瘦多取芯钻头和圆形槽边缘的中心麻花钻切削力预测模型。巴特纳格尔ñ(2004年)和其他研究使用四个不同的钻头钻各类各向异性纤维增强复合材料工件的意外损坏,一个钻井轴向力和扭矩模型。萨胡水库(2004年)和芯片组制成的其他断路器槽切削力预测模型,以四种不同的断屑槽钻校准,可以适用于任意形状的断屑槽位使用的模型锥演习。 Elhachimi M(下一九九九年)和直角斜切割的综合应用模式成立一个高跨领域的切削力模型位速度的转速4000r/min〜18000r/min,为0.12毫米饲料,/ ṛ〜0.36毫米/ r是实验结果与模型预测值一致。王唱片(1998年),由主旋翼的组成提出了别人,凿整个位动态力学性能的机组振动分析工具的优势,并据此建立了一个动态轴向力和扭矩预测模型振动钻削过程。

随着研究的不断深入,研究人员发现,由于结构性差异,在过去已建立了力学模型不应适用于新型的钻探。为此,Stepenson伤残津贴(1992年)一个单位的大量实验校准锥切削刀具车削力模型,设置任意形硬质合金刀片或一个灰铸铁镶嵌硬质合金钻头钻孔时,在主旋翼扭矩,轴向力和径向力预测模型。林的GC(1982年)和沃森铁(1985年)指出,钻探转矩和轴向力是由于低估了芯片的干扰,这一发现最终导致细胞合成工具选择的非线性,而且使用分析方法建立了复杂的切削力模型形刀片钻头可能。王JL(1994年),研究了削减芯片干扰的过程中,非线性综合工具单位申请,经验上的切削力模型的任意切削力模型伞刀形位刀片的一个小组,专门。

位除了基本的几何形状,一些因素钻井过程将会对钻井的影响力。 1996年,Chandrasekharan五,谁考虑了钻头制造和研磨,如两主旋翼线误差,半径误差,轴向位移等,建立一个完整的三维牙轮钻头切削力模型集,然后扩展对任意形状预测钻头(如钻探小组)切削力。 Sriramṛ,考虑到钻磨钻上的影响力条件安装错误,建立了钻径向力预报模型。 2001年,龚YP和埃曼亩建立全面的,考虑到钻头的几何特征,研磨和安装错误以及主要叶片和跨位斜切割刀片的厚度和切割区的动态影响微孔钻头轴向力,扭矩和径向力模型。钻削力

Bits and drilling study the history, current situation and development trend of

Human understanding and use of the bit of history can be traced back to prehistoric times.燧人氏”钻木取火” stone used by drilling, can be seen as the most primitive bit. Modern industrial processing of the twist drill is widely used (commonly known as bits), is a complex shape of the real workpiece hole processing tools, was born in more than 100 years ago. Now, the annual consumption of all kinds all over the world hundreds of millions of bits. According to statistics, in the U.S. automobile manufacturing industry, machining processes in the proportion of drilling approximately 50%; while in the aircraft manufacturing industry, the proportion of drilling process is even higher. Despite such widespread use of drill bits, but is well known that drilling is the most complex machining methods. Precisely because of this, people have committed to drill bits and drilling to improve the process of research. Based on available English literature, the two grooves of the twist drill and drilling technology research history, current situation and development trends are reviewed.

1. The main areas of research and technical issues

in recent decades, it is about bits and drilling bits apart from the research materials of improvements, mainly concentrated in the following five aspects:

① bit mathematical models and geometric design research: including the spiral groove, flank, the main blade and chisel set up the mathematical model, the horizontal cut-off shape with the drill point of the optimization of structural parameters, the cutting angle (distribution) of the calculation and control, the bit structure static and dynamic characteristics analysis of drill point geometry and the cutting and performance study on the relationship between Chip.

② bit manufacturing methods research: including the drill bit geometric parameters and Flank the relationship between grinding parameters set up and optimization, manufacturing precision and grinding drill evaluation of the quality and manufacturing errors of measurement and control, drill spiral groove processing tools for the design and calculation truncatus, bit processing equipment, especially CNC grinding machine with the processing software development.

③ drilling drilling process and the quality of research: the impact of drilling process, including a variety of factors and the emergence of a variety of physical phenomena analysis, modeling and monitoring (such as drilling, and cutting edge of stress and temperature distribution measurement, modeling and forecasting); drill wear, drill breakage mechanism and life studies; bit of deformation, deflection, at the time of skidding into the drill and drill point swing phenomena research; drilling process (such as vibration drilling, high-speed drilling, deep hole drilling, drilling, such as the stability of the process) and the quality of drilling (hole location accuracy, straightness, surface roughness, Cylindricity, diameter, orifice deburring, etc.).

④ drilling mechanism with a wide range of high-performance drill bits (such as base drilling, gun drilling, drill bit do the cutting, porous, deep-hole drill bit, long drill bits, drill bits turning, synthetic material processing bits, woodworking drill bit, multi-spiral groove bit, etc.).

⑤ drilling process model verification and drill performance evaluation process automation, cutting conditions and drill bit shape selected database and knowledge base, such as set up.

At present, the most dynamic areas of research are bit mathematical model, the geometric design and manufacturing methods (equipment) research, drilling and drilling process modeling the quality of research.

2. Bit mathematical model and geometric design research

2.1 bits

set up the mathematical model of the mathematical model of drill bit geometry of the design, manufacture, cutting performance analysis and modeling of drilling process foundation. Mathematical model of the first bit by the Galloway DF proposed in 1957. He deduced the linear blade drill rake face of the parameter equation, give the main blade before and after the beveled chisel edge angle and the definitions, calculation formula and the measurement method, the “flank of the drill bit in the grinding process interaction with the grinding wheel after grinding cone formed part of “point of view. aided design program. 1972, Armarego EJA and found Rotenbery A: flank conical grinding method has four independent grinding parameters, and give a general geometric parameters of the drill point is only 3, so should not only determine the Drill Flank The shape and grinding parameters. To this end, they proposed to flank the end of gap angle as supplementary geometric parameters to obtain the only solution of grinding parameters. 1979, Tsai WD, and Wu SM prove: cone drill, Racon drill bits, screw bits and drill bits, etc. Bickford flank can be used to express conicoid and proposed that the drill geometry integrated mathematical model, the model can be used to control the grinding process. 1983, Radhakrishnan L et al proposed Cross Drill Drill flank of a mathematical model. They will flank flank into the first and second flank: on the first flank to Tsai model, set up an improved cone model; on the second flank, set up a a plane model. Fugelso MA has put forward cylindrical drill point of the mathematical model. 1985, Fuh KH and others set up a quadratic surface with the drill flank express mathematical model in order to use a computer designed to be ellipsoid, hyperboloid, cone, cylindrical or any combination of them.

a long time, people have to twist the main blade is designed to a straight line. 1990, Fugelso MA found that due to requirements of the main cone drill to straight edge, so close to the main Department coring blade angle becomes too small, if, before grinding to bits around its own axis of rotation 5 ° ~ 10 °, we can solve this problem, only the main blade will become slightly curved. The same year, Wang Y will be regarded as the main blade curves, the use of polynomial interpolation methods set up the spiral drill rake face geometry model. 1991, Lin C and Cao Z, a suitable straight edge and curves using conical, cylindrical and planar flank the integrated mathematical model of the twist drill. 1999, Ren KC and Ni J proposed binomial express arbitrary shape curves of the main blade, drill flank before the introduction of a new mathematical model, and vector analysis methods, set up a conicoid flank the grinding parameters and geometry the relationship between parameters.

2.2 bits of structural optimization

as a result of the extensive use of the cutting performance of the cone drill is not satisfactory, it has been working on its structure (parameters) and the grinding methods of improvement, has made more than 200 kinds of different shape with the drill bit so as to improve its cutting performance. One, Shi HM, who put forward by changing the main blade to control the angular distribution of the main pre-edge method, and in 1990 as ambassador to drill the development of the main blade on the anterior horn of the points are up to the maximum of the curve may twist drill blade. 1987, Lee SJ bit skewed considering the conditions, to eliminate the drilling process the drill point swing phenomenon as the goal, put forward the structure of the drill bit to optimize the design method. 1995, Selvamhe SV and Sujatha C twist deformation in the study, the use of finite element method drill geometry optimized drawn so that the smallest bit of structure deformation parameter optimization value (drill diameter of 25mm) as follows: helix angle 39.776 °, chisel angle Ψ = 54 ° ~ 80 °, front angle 120 °. 1997, Chen WC, a special cut-off thick-shaped coring drill, we have sufficient torsional stiffness, but also has a reasonable cross-blade main blade and the angular distribution of the former. In 2005, Paul A, such as man-made to ensure that the Optimize drill machinability, a grinding parameters based on the new drill point model, and its conical drill point, Racon drill point and spiral drill point surface is optimized to them to minimize the cutting force. spiral groove

2.3 truncatus truncatus and processing tools for the calculation of

1975 years, Dibner LG can be simplified to a grinding wheel cut-off spiral-shaped groove, the groove improve processing accuracy and be completely ruled out the effects of wheel diameter and changes in methods. 1990, Ehmann KF proposed based on the principle of differential geometry and kinematics of the spiral groove twist drill for machining tools truncatus method. 1998 ~ 2003, Kang DC, and Armarego EJA machining of spiral grooves “are” and “inverse problem” ( “from a trench truncatus truncatus seek tools” and “by the tool truncatus truncatus seek trench”) conducted a study on a straight-edged twist spiral grooves in the design and manufacture of computer-aided geometric analysis. About

2.4 base drilling and micro-drill study

1982 years, Shen J et al set up a group of drilling the first mathematical model. Using this model, it can be repeated to drill grinding group. 1984, Chen L and Wu SM group of nine kinds of typical drill conducted a study to improve the base of the mathematical model of drilling, drilling for the group of computer-aided design possible. 1985, Hsiao C, and Wu SM made with computer-assisted group of drilling carried out to optimize the design of specific methods. 1987, Fuh KH presents a comprehensive conicoid finite element method model and the design and analysis of cluster drilling methods. Liang EJ is a Knowledge-based technology group drill grinding CAD / CAM integrated system. 1991, Liu TI uses a two-stage strategy for the design and optimization of a processing machine axis injection hole drilled by group. 1994, Huang HT group and others derived drilling cutting edge work of law and the posterior horn anterior horn of the formula, put forward for consideration of edge and arc transition zone between the edge of the base drilling precise geometric model. 2001, Wang GC and others block the application of a tilted three-dimensional approach, set up a group of drilling a new mathematical model to solve the existing model of cross-edge geometry of the problem of uncertainty, and ensure the design of the base drilling machinability .

1992 onwards, Lin C, Kang SK, Ehmann KF and others Chyan HC Study Group, composed of micro-drill bits on a systematic study. In 1992, they set up a planar micro-drill point mathematical model of the corresponding grinding method. In 1993, they raised spiral surface micro-drill point grinding of mathematical models and methods, and found that surface micro-spiral drill point and cutting performance in the geometric aspects are better than commonly used micro-Plane Drill. In 1997, they pointed out: micro-helical drill point with a sharp planar micro-drilling, compared with two advantages: ① in the same point of the distribution of the work of cutting conditions, it allows greater feed rate; ② grinding method more simple, not vulnerable to the effects of grinding error. In 2002, they produce processing microporous with curve-shaped spiral blade flank series Drill.

3. Drilling Force Modeling

3.1 Drilling Force

the history of modeling in the past few decades, people reported a lot of drilling force prediction methods, most of which are applied to the standard twist drill of the. Due to the lack of advanced computers and measuring equipment, early research focused on the establishment of a simple empirical model of torque and axial force, the model parameters is to drill geometry parameters (such as drill diameter) and cutting parameters, modeling method is adopted a large number of cutting experiments using statistical methods of drilling force fitting empirical formula.

using analytical methods of drilling force model set up as people are cutting in-depth understanding of the process of gradually emerging. 1955, Oxford recorded by micro-photographs of the main drill chisel edge and the chip deformation process, and through experimental discovery: drilling process, drill point in the existence of three main regions of the cutting, that is, the main cutting edge area, the first Second Cutting Edge (Cross Edge) Cutting area and near the core zone characterization. Later, Shaw MC and Oxford CJ Jr proved chisel in the importance of drilling, because it produced a 50% ~ 60% of the axial force. 1966, Cook NH proposed a semi-analytical method with derived formula drilling method. Shaw MC (1962,1984), in chip deformation mechanism of an in-depth study on the basis of a bit of chip deformation of the main blade model. Williams AR (1974 years) has proposed a tool based on the single-point two-dimensional model of the drill cutting blade main cutting force model, and to determine the drill diameter depiction area. Armarego EJA (1972 years) the application of oblique cutting theory, put forward a Plane Drill cutting force prediction model. Wiriyacosol S (1979 years) and others under the chip deformation of thin shear zone (shear plane) theory, will drill the main blade and chisel edge and cutting conditions as a series of modules on the right-angle bevel or a combination of cutting tool, through accumulation of these modules tool to forecast drilling cutting force, namely the linear cutter unit synthesis method. Shear plane in the basis of theory, Oxley CJ Jr (1959,1962 years), Armarego EJA (1972,1979) and Waston AR (1985 years), respectively, set up a different drilling force model; Stepenson DA (1988,1989 years) made the mathematical calculation met…
