What Is Computer Aided Manufacturing?

Over the past decade, manufacturing processes all over the world have undergone some dramatic changes. The introduction of automated systems and computer technology has allowed industries to significantly increase their productivity. CAM is the abbreviation for Computer Aided Manufacturing. Computer aided manufacturing accurately converts product drawing or the object into a computer readable code format, enabling the machine to manufacture the product. Computer aided manufacturing can be used in different machines like lathes and milling machines for manufacturing the related product.

A computer aided manufacturing system allows the manufacturer to systematically communicate work instructions to the machine. CAM has evolved from a technology referred to as the Computer Numerical Control (CNC), invented in the 1950s. CNC performed a set of coded instructions in a punched paper tape.

Computer aided manufacturing facilitates effortless and quick computer programming and faster execution of design changes. The computer aided management system integrates the computer aided design systems and controls tasks that involve order placement, scheduling, and replacement of tools. The implementation of CAM system leads to overall increase in efficiency of the manufacturing process. CAM systems are used in the automotive, aviation and furniture manufacturing sectors and areas such as mechanical engineering and electronic designing. Another significant benefit of using the computer aided management system is that it allows customization of the manufacturing process for creating client specific designs.

A computer aided manufacturing system requires a 3D environment for making it compliant with CAD systems. The CAM system can cost $18,000 or more along with the appropriate software. CAM allows automated integration of the manufacturing procedure with other mechanization systems such as Computer-Integrated Manufacturing (CIM), Integrated Computer-Aided Manufacturing (ICAM), Flexible Manufacturing System (FMS), Direct Numerical Control (DNC), and Manufacturing Process Management (MPM). Repetitive tasks involved in the manufacturing process are delegated to machines using the CAM system, allowing workers involved to concentrate on quality control and productivity.

History of Computer Aided Manufacturing

Computer Aided Manufacturing (CAM) is one of the software automation processes that directly convert the product drawing or the object into the code design that enables the machine to manufacture the product. It is used in various machines like lathes and milling machines for the product manufacturing purposes. It allows the computer work instructions to communicate directly to the manufacturing machines.

The mechanism of CAM developed from the Computer Numerical Machines (CNC) in the early 1950?s. These systems were directed by a set of coded instructions in a punched paper tape. The proposal to develop the first numerically controlled machine was commissioned to the Massachusetts Institute of Technology (MIT) from the US Air Force in the year 1949. The entire proposed idea of developing this machine was demonstrated in the year 1952.

The motivation factor in developing these kinds of numerically automated machines involves the expensive costs in manufacturing the complex curved geometries in 2D or 3D constraints mechanically. The development of these machines considers the factors like easier programming in CAM and easy storage of programs. A program can be changed easily and avoid manual errors. Numerically controlled machines are safer to operate, and the complex geometry comes at a reasonable price.

James T. Parsons proposed the concept of the numerical control operations during the year of 1948. In 1950, the MIT servo mechanism lab developed the Numerical Control (NC) milling project. The remaining program parts were released in the later period of 1952 along with the first successful demo version. After 1955, major companies in the industry developed their own machine designs.

IBM?s Automatic Tool Changer in the year 1955, G & L?s first production of the skin-miller in the year 1957, and the machining center developed by K & T have all been considered to be major developments to promote the technology with more benefits. CAD drafting and the sculptured surfaces were developed in the year 1965; 7,700 NC?s were also installed during the same year.

During the year 1967, the concept of developing the CNC machine was proposed. The existence and the major development of the CAD/CAM machines evolved during the year 1972. 3D CAM/CAD systems were introduced in 1976. Expert CAM/CAD systems were developed in the year 1989. The major development of the CAM systems provides you with easier manufacturing of objects with high efficiency.

Industrial Information - High Speed Milling Machines

High speed machining is a proven stipulation characterized by low cutting forces and high metal removal. High Speed Milling is a technique used in the CNC Milling Industry that combines high spindle speeds with increased feed rates. This results in a high chip-forming rate and lower milling forces, producing an improved surface quality and closer tolerances. In high speed milling, the electronics can make all the difference. The right CNC coupled with other elements of the control system can let a slower machine mill a given form faster than a machine with a higher top feed rate.

1. High Speed Uses

High-speed CNC milling is used, for example, to machine the titanium rotors of the first high-pressure compressor stages of the EJ200 engine. High speed CNC milling allows cost-effective milling of the airfoil geometry from the solid. By subsequent finishing operations the planned surface finish is achieved. The CNC milling which caters to high speed must be structured with an axis movement system that is suitable for machining.

2. Axis Movement

The high-speed CNC milling machines required for the process must be fitted with an axis movement system suitable for machining blisks, which should be at least 5 axes simultaneously, depending on the milling task involved and an efficiently high-speed control system.

3. 3D Surfaces

High Speed CNC milling machines working on 3D surfaces in any materials produce a finer surface finish and higher accuracy in less time that the traditional milling machine. Acceleration is the most critical factor that affects the high speed machining. Since one or more axis are always increasing or decreasing velocity in a 3-D cut, ultimate feed rate is directly related to acceleration

4. What Can A High Speed Control Possibly Do?

A CNC milling machine which possesses a higher structural stiffness has a greater potential acceleration rate. Box shaped high speed CNC milling machine, like Bridge and Gantry is the mostly widely used types of High speed CNC milling tools. The overhead type Gantry exudes the highest stiffness, acceleration and accuracy among other high speed CNC milling tools. Due to its scalability, this machine type is available in sizes to match the work piece, from small to large.

In usual terms, it simply gives you the ability to finish one task faster and move along to the next sooner, making work output higher. In drilling and tapping, this can result in faster hole-to-hole times, quicker spindle reversals for tapping, and substantial cycle-time reductions. The most dramatic benefits, though, come in 3D designs machining. Few, drilling and tapping jobs require a million lines of machine codes. In molds, dies, patterns, and prototypes, complex surfaces comprising a million or more line segments are not at all uncommon. Saving just a fraction of a second per move can result in substantial cycle-time improvements.

5. Downsides - When Is Fast Too Fast?

But despite all these benefits, in high milling, the tool path segments can be so short that a machining center moving at a high feed rate can?t accelerate or decelerate fast enough to make direction changes accurately. Corners may be rounded off and the work piece surface may be gouged. Look-ahead is one answer. Look-ahead capability can let the CNC read ahead a certain number of blocks in the program, to anticipate sudden direction changes and slow the feed rate accordingly.

6. Additional Benefits:

- Improved accuracy
- Better fit
- Superior finish
- Better life
- Produce more work in less time
- Improving the accuracy and finish
- Reducing polishing and fitting time
- Tools simply last longer because their chip load is more consistent

Cnc Machine Buying Guide

 

CNC refers to the computer controls of a machine. With the help of a program code, it will be easier to replicate same parts. It is a great innovation in the field of manufacturing that makes mass production more efficient and practical. That is why companies, large or small, must exert effort to find a CNC machine that will best suit their needs.

Here are some tips on how you can get the best CNC machines.

- Buy and choose with the help of buyers representative. A buyers representative has been made to cater to the following needs and give advantages to CNC machine users -

1. To allow users to save time in negotiating

Most people who would buy CNC machines will have to settle with getting quotations from two to three manufacturers to save time and to avoid the hassle of talking to a lot of sales representative.

By asking professional help from someone who knows a lot about CNC machines and manufacturers, you will just coordinate with only one party- the buyers representative. They will be the one who will shoulder all the talking and negotiations for you.

And since they regularly collect updated quotations from the CNC machine manufacturers, it will take lesser time for you to get information regarding the CNC machine of your choice.

2. To check the quality of the products that they are referring to buyers

Buyers representatives exert effort to check that the machines that they will be referring to buyers are of good quality.

3. To offer a large variety of machines from different machine manufacturers

Most people do the common mistake of asking for quotations from the well- known (and expensive) brands in the market when they have the options of buying other brands that are as efficient yet cheaper than the ?mainstream? brands.

Buyers representative offer quotations from less prominent CNC machine manufacturers that has cheaper price as well. In this way, the buyers representative also gives equal playing fields for all CNC machine manufacturers, both in the large- scale and medium scale.

4. To allow buyers opportunities to get the best deal for their money and save some too.

All buyers would like to get the best thing that their money can buy. Also, all buyers would also prefer to save their hard- earned money without sacrificing efficiency and quality. Here are some ways buyers representative can help you save money -

- The buyers representative only charge 5 percent of the cheapest CNC machine that meets the buyers requirements. That is a small price to pay for the assurance that you will get a wonderful CNC machine that will cater to your needs.

- The buyers do not have to settle in buying prominent brands and pay for the brand name. With lesser money to spend, one can get a machine as efficient as the prominent brands.

- By forming buying groups, buyers representative can also negotiate with manufacturing companies to give discounts to prospective buyers.

- With greater competition among the manufacturers, there will be better quality of products and more affordable prices.

- If getting help from buyers representative is not your choice, you can always do it yourself. The general rule in buying CNC machines is to be familiar with all the parts first then everything else will follow.

1. Make sure that the following parts are intact and correctly attached to the CNC machine to ensure the perfect working condition of the machine -

- the safety shield (a plastic that cover that protects the working space),

- the tool or drill bit (the part that does the cutting),

- spindle shaft (the part that holds the tooldrill bit),

- the spindle motor (the part that drives and controls the cutter),

- the vertical or upright column ( holds the pieces together) and

- the control box.

2. Always look for the emergency stop button in your CNC machine. This is to ensure that when an error is made, the machine can be stopped manually to prevent further damages from happening.

3. Big control guides are preferred so it will be easier for user to refer to it. It will also be helpful for operators who have poor eyesight too.

4. The plastic that comprises the shield must be made from sturdy polycarbonate.

Guide To CNC Machines

 

CNC machines are used in a variety of industrial settings and in woodworking shops. Most are out of the price range for the individual user, but can be purchased used for about half the price. These machines increase speed and accuracy when doing large jobs or repetitive tasks.

How CNC Machines Work
?
CNC machines are used in a variety of industry, manufacturing processes and woodworking shops. CNC routers are used for drilling holes. Some machines have the capability of holding several tools. This allows them to perform more than one operation at a time. They save time and improve accuracy.

CNC stands for Computer Numerated Control. This technology was first seen in the 1970s. The machines need to be programmed and set up properly before operation. Once the initial set up is completed, they are fairly easy to operate and keep running.

In CNC routers, they can be programmed to drill holes in an automatic fashion. This is faster and more accurate over several pieces than in manual drilling. The results are more uniform. This method is very beneficial for larger jobs that require a lot of drilling. Manual drilling can become tiring and when the operator becomes tired, the results can become inconsistent.
?
Types of CNC Machines
?
A CNC lathe is a good piece of equipment for cutting wood. These come in models ranging from fifteen to forty horsepower. The amount of power you need depends on the amount of wood you will use with the lathe. The best models operate in several different modes, from completely manual to all CNC. This allows you to tailor the machine?s operation for each project.

A Bridgeport mill is the best in milling technology. Mills are used in many industries, both large and small shops. They are efficient and reliable. Bridgeport mills are built to last a lifetime. However, they are very expensive. The price is out of the range that most people can afford.

The CNC mill is a specialty piece of equipment. It uses computer programming and robotics for accurate operation. The results are more accurate than any person could ever achieve. For this reason, Bridgeport mills are often used in the airline industry. Once the specs are entered, the CNC decides which tools need to be used and automatically changes the tools as needed.

Engraving equipment is made to engrave a variety of materials including glass, stone, metal, wood, composites and many others. The machines mark and engrave with more accuracy than could ever be achieved by hand. Everything from large signs to small lettering can be done, depending on your needs.
?
Buying Used units
?
CNC equipment is very expensive and out of the price range of most people. Buying used CNC electronics is an affordable option for some people. You can save nearly 50% or more on some equipment. Be careful when buying used, you want to be sure the equipment is in good condition.

A better option is to look for refurbished equipment. These machines have been inspected at the factory. Any broken or damaged components are replaced. In many cases, the machine is painted and new decals are applied. It?s like getting a new machine for a significantly reduced price. Often, you will get a one year warranty with reconditioned equipment. This gives you time to be sure it is working properly and if not, you can get it fixed for free. Charles Mahoney publishes many articles for the website http://www.inside-woodworking.com . He writes on topics from CNC technologies and other areas in this field.

The Mini CNC Machine

 

The mini CNC machine gives the manufacturer a way to reduce cycle time. The mini CNC machine helps the manufacturer to avoid a long void between the end of one operation and the start of the next operation. The manufacturer who decides to purchase a mini CNC machine has chosen to apply the principles of cycle time to the area of production machinery.

The nature of the mini CNC machine creates three ways by which miniaturization can pave the way for cycle time reduction. This article will list three ways by which a manufacturer can reduce cycle time. It will also provide details concerning how the mini CNC machine permits the manufacturer to apply the principles of cycle time reduction to the operation of the mini CNC machine, and ultimately to the process of machine production.

The effort to reduce the manufacturers cycle time begins with an attempt to minimize the amount of time that operators spend loading and unloading various materials. The operator of a CNC machine will work more efficiently if he or she is able to minimize the workplace loading and unloading. This minimization is achieved through use of the mini CNC machine.

The operator of the mini CNC machine can save time by using large bed sizes and a small footprint. The operator of a mini CNC machine will save money by loading into the machine a wide piece of material and then limiting each process (cutting, engraving, routing, and drilling) to a small footprint.

The operator of a CNC-based piece of equipment can reduce cycle time by reducing the tool maintenance time. Such a reduction is made possible by the mini CNC machine. The small size of the miniaturized machines facilitates the creation of multiple design options. The large number of options leads to creation of a generous number of spare parts. Meanwhile the surplus of spare parts guarantees the ready replacement of any malfunctioning parts.

The operator of a mini CNC machine also reduces cycle time by decreasing the program execution time. The clamping of small elements to the mini CNC machine and the automation of the tiny machine parts leads to a lowering of operator intervention. Whenever operators can afford to devote less time to matching the quality of a previous result, then the manufacturer saves money.

It thus becomes obvious that the characteristics of the mini CNC machine guarantee the application by the operator of the principles of cycle time. Three aspects of any CNC program fall under the control of the product manufacturer.

1) The time required for workplace equipment to accomplish the loading and unloading of the material that requires a transformation (a cutting, drilling, routing or engraving),
2) The length of the program execution time,
3) The length of the tool maintenance time.

The ability of a mini CNC machine to substantially alter any of the above three aspects could lead to a reduction in cycle time. A reduction in cycle time could improve performance of the process machinery.

CNC Cutting Machine

The operators of the present-day CNC cutting machine demonstrate many of the same skills as those possessed by various traditional craftsmen. The operators of the CNC cutting machine include the men and women who design and make cabinets, woodwork, signs, and a whole range of metal, solid surface and plastic objects. The manufacturers who employ these operators know how important it is to have a good quality CNC cutting machine.

A good quality CNC cutting machine has a cutting table that covers the area bounded by a length of four feet and a width of eight feet. A quality table can handle satisfactorily a standard 4 x 8 plate of metal, wood, plastic, glass, or stone. A table that lacks a sufficient length or width will make it necessary for the operator to repeatedly reposition the plate. Operators of the CNC cutting machine refer to such repositioning as indexing.

A good basic CNC cutting machine does both plasma and oxyfuel cutting. Refinements on a basic cutting machine might provide it with the ability to perform other functions, functions such as:

-spotting holes for drilling
-drilling aluminum
-cutting a shape in the sides or end of tubing
-routing wooden shapes.

Other modifications on a CNC cutting machine might be directed at installation of the equipment for laser or water jet cutting.

The selection of a CNC cutting machine will be primarily determined by the nature of cutting that will be performed by the machine operator. For some operations, it will be necessary to do only straight cutting. For other operations, the cutting machine must perform bevel cutting. Bevel cutting allows the operator to trim, reduce, shave, and pare the material in the plate.

Both types of cutting will subject the CNC cutting machine to a fair amount of wear and tear. The manufacturer therefore needs to purchase a machine with adequate customer support. Such support should include the availability of spare parts. An absence of spare parts could require that the electronics of the CNC cutting machine undergo a retrofitting.

A need for retrofitting would deprive the operator of important production time. The need for retrofitting would diminish the quantity of goods that could be sold to the consumer. The need for retrofitting leads to a decrease in the amount of time that the operator will be spending at the CNC cutting machine. That is why the availability of spare parts for a malfunctioning CNC cutting machine remains one of the two chief concerns of the manufacturer. A second prime concern is the size of the cutting table.

The operator of a CNC cutting machine that needs to spend a large percent of time indexing will not have much time to spend on the actual cutting. Hence, the manufacturer will have much less product. Fewer products from the manufacturing facility translate into fewer products on the shelf. Consequently, the need for operators to spend time indexing can prove a detriment to the company?s bottom line. A good sales volume reflects the well-planned purchase of a CNC cutting machine.Peter Vermeeren is the owner and webmaster of: Machines and Tools and Airsoft GOT | Tactical Gear | Military Supplies
