Introduction to Finite Element Analysis A Brief History
Finite Element Analysis (FEA) was first developed in 1943 by R. Courant, who utilized the Ritz method of numerical analysis and minimization of variational calculus to obtain approximate solutions to vibration systems. Shortly thereafter, a paper published in 1956 by M. J. Turner, R. W. Clough, H. C. Martin, and L. J. Topp established a broader definition of numerical analysis. The paper centered on the "stiffness and deflection of complex structures". By the early 70's, FEA was limited to expensive mainframe computers generally owned by the aeronautics, automotive, defense, and nuclear industries. Since the rapid decline in the cost of computers and the phenomenal increase in computing power, FEA has been developed to an incredible precision. Present day supercomputers are now able to produce accurate results for all kinds of parameters. What is Finite Element Analysis?
FEA consists of a computer model of a material or design that is stressed and analyzed for specific results. It is used in new product design, and existing product refinement. A company is able to verify a proposed design will be able to perform to the client's specifications prior to manufacturing or construction. Modifying an existing product or structure is utilized to qualify the product or structure for a new service condition. In case of structural failure, FEA may be used to help determine the design modifications to meet the new condition. There are generally two types of analysis that are used in industry: 2-D modeling, and 3-D modeling. While 2-D modeling conserves simplicity and allows the analysis to be run on a relatively normal computer, it tends to yield less accurate results. 3-D modeling, however, produces more accurate results while sacrificing the ability to run on all but the fastest computers effectively. Within each of these modeling schemes, the programmer can insert numerous algorithms (functions) which may make the system behave linearly or non-linearly. Linear systems are far less complex and generally do not take into account plastic deformation. Non-linear systems do account for plastic deformation, and many also are capable of testing a material all the way to fracture.
How Does Finite Element Analysis Work?
FEA uses a complex system of points called nodes which make a grid called a mesh (Figure 2). This mesh is programmed to contain the material and structural properties which define how the structure will react to certain loading conditions. Nodes are assigned at a certain density throughout the material depending on the anticipated stress levels of a particular area. Regions which will receive large amounts of stress usually have a higher node density than those which experience little or no stress. Points of interest may consist of: fracture point of previously tested material, fillets, corners, complex detail, and high stress areas. The mesh acts like a spider web in that from each node, there extends a mesh element to each of the adjacent nodes. This web of vectors is what carries the material properties to the object, creating many elements. A wide range of objective functions (variables within the system) are available for minimization or maximization:
Mass, volume, temperature Strain energy, stress strain Force, displacement, velocity, acceleration Synthetic (User defined)
There are multiple loading conditions which may be applied to a system. Next to Figure 3, some examples are shown:
Point, pressure (Figure 3), thermal, gravity, and centrifugal static loads Thermal loads from solution of heat transfer analysis Enforced displacements Heat flux and convection Point, pressure and gravity dynamic loads
Each FEA program may come with an element library, or one is constructed over time. Some sample elements are:
Rod elements Beam elements Plate/Shell/Composite elements Shear panel Solid elements Spring elements Mass elements Rigid elements Viscous damping elements
Many FEA programs also are equipped with the capability to use multiple materials within the structure such as:
Isotropic, identical throughout Orthotropic, identical at 90 degrees General anisotropic, different throughout
Types of Engineering Analysis Structural analysis consists of linear and non-linear models. Linear models use simple parameters and assume that the material is not plastically deformed. Non-linear models consist of stressing the material past its elastic capabilities. The stresses in the material then vary with the amount of deformation as in Fig 4. Vibrational analysis is used to test a material against random vibrations, shock, and impact. Each of these incidences may act on the natural vibrational frequency of the material which, in turn, may cause resonance and subsequent failure. Fatigue analysis helps designers to predict the life of a material or structure by showing the effects of cyclic loading on the specimen. Such analysis can show the areas where crack propagation is most likely to occur. Failure due to fatigue may also show the damage tolerance of the material (Figure 5). Heat Transfer analysis models the conductivity or thermal fluid dynamics of the material or structure (Figure 1). This may consist of a steady-state or transient transfer. Steady-state transfer refers to constant thermo properties in the material that yield linear heat diffusion.
Results of Finite Element Analysis FEA has become a solution to the task of predicting failure due to unknown stresses by showing problem areas in a material and allowing designers to see all of the theoretical stresses within. This method of product design and testing is far superior to the manufacturing costs which would accrue if each sample was actually built and tested. Introduction to ANSYS The ANSYS program is a computer program for finite element analysis and design. The program is used to find out how a given design (e.g., a machine component) works under operating conditions. The ANSYS program can also be used to calculate the optimal design for given operating conditions using the design optimization feature. The ANSYS program is a multi-purpose program, meaning that you can use it for almost any type of finite element analysis in virtually any industry - automobiles, aerospace, railways, machinery, electronics, sporting goods, power generation, power transmission, and biomechanics, to mention just a few. "Multi-purpose" also refers to the fact that the program can be used in all disciplines of engineering - structural, mechanical, electrical, electromagnetic, electronic, thermal, fluid, and biomedical. The ANSYS program is also used as an educational tool in universities and other academic institutions. ANSYS software is available on many types of computers - PCs (personal computers), workstations, minicomputers, superminis, mainframes, super mainframes, etc. Several operating systems are supported, as are a multitude of graphics devices.

CNC PROGRAMMING PROGRAMMING STRUCTURE Main Programs are written using I.S.O. address codes listed below: Addresses – A FANUC compatible program number line is written in the following format: O ØØØØ Where, O is the Address Code. ØØØØ is the four digit program number N
refers to the block number.
G
refers to the G code (Preparatory function).
X refers to the absolute/incremental distance travelled by the slide tool in the X axis direction. Y refers to the absolute/incremental distance travelled by the slide tool in the Y axis direction. Z refers to the absolute/incremental distance travelled by the slide tool in the Z axis direction. F
refers to the feed rate.
M
refers to the M code (Miscellaneous function).
S
refers to the spindle speed.
T
refers to the tooling management.
; is the End Of Block (EOB) signal. Each block, or program line, contains addresses which appear in this order: N,G,X,Y,Z,F,M,S,T; This order should be maintained throughout every block in the program, although individual blocks may not necessarily contain all these addresses. The organization of blocks of data within the program follows a layout. Again, it is recommended that the programmer keeps to this program layout.
Differences between a sub and main program: 1) A sub program does not have a billet size definition at the top of the program listing. 2) A sub program is ended by the M99 code. 3) Sub programs can also call other sub programs into operation.
Sub Program: To call a sub program the M98 code is used followed by PØØØØ (the number of the sub program required). For example, M98 P2ØØØ This command is read call program number 2ØØØ. A sub program call command (M98 PØØØØ) can be specified along with a move command in the same block. For example, GØ1 X42.5 M98 P1ØØØ; At the end of a sub program, the M99 code is entered. This returns control to the main program. The M99 code will return control to the next block after the M98 sub program call block in the main program. If the code M99 PØØØØ is entered, control will pass to the main program at a block with the N number equal to that of the P number stated after the M99 code. For example, M99 PØ16Ø; This command is read return to the main program at block number NØ16Ø. A call command can be set to call a sub program repeatedly. This call can specify upto 999 repetitions of a sub program. A sub program repeat command is written in the following format: M98 PØØØ ØØØØ where, M98 is the call command. PØØØ is the number of times the sub program is to be repeated. ØØØØ is the sub program number. For example, M98 P1ØØØØ1; This command is read call the sub program number ØØØ1 ten times. When the repetition is omitted, the sub program will be called once only.
