CNC And CAD - Computer Aided Design

CAD stands for Computer Aided Design or Computer Aided Drafting. CAD was developed in the early 60s. Today it is the premier way to design, develop and optimized products. People use CAD every day to design virtually every product you see. Generally, designers use CAD to design a product, and then produce prints to manufacture that product. A print is a picture of a part or assembly that is very exact. It includes the dimensions and a parts list used to manufacture a product. CAD is the use of computer based software packages that assist engineers, architects and other design professionals in their designs. CAD is the part of the main designing process and involves both software and sometimes hardware. Current software packages range from 2D vector based drafting systems to 3D solid and surface modelers.

Computer Aided Drafting software packages can generally be broken into two groups. The groups are 2-D drafting packages or 3-D drafting packages. Most all software packages are moving to 3-D design. 3-D design is really the next generation of CAD. Utilizing 3-D design, engineers can make a model of their product. They can then look over this model for any apparent defects before it is ever made.

CAD is used to design, develop and optimize products. CAD is mainly used for the engineering of models and/or drawings of components. It is also used throughout the engineering process from concept to design of products. These products can be used by end consumers or used in other products. For example, you can design a bolt in CAD, and then use it in a Sub-Assembly in a planetary, which is a part of an earth-moving machine. CAD is also used in the design of tools and machinery. Finally, it is used in the design of all types of buildings from sheds to shopping malls.

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.

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.
