The two words CAD CAM have been thrown a lot in the manufacturing industry, but what exactly is it? When we say CAD / CAM, do we really know what we are talking about? According to my experience, many of us do not. A simple definition is a good starting point. Computer aided design and computer aided manufacturing.
Look around, whether you are at home or at the office. Almost everything you see around you may be designed on your computer. In addition to the buildings made before the 1970s and any antique furniture that may be in the home, a large part of the items we use every day are designed using CAD.
Automotive and aerospace design was responsible for the development of early CAD systems in the 1960s and 1970s. They are very expensive systems and cost more than $100,000 per station. With the development of the PC, all of this has changed, and the purchase price of the CAD system is between $500.00 and $5,000.00.
Even with expensive additional options, the cost of a single CAD seat will not exceed $20,000 unless it is used for some very high-end professional features. The development of CAD CAM software is in parallel with the rise of personal computers, making this type of software affordable for the average manufacturer.
So how about CAM? I think you can say that there is no CAM without CAD. No electronic design, no CAM system can run. Sometimes the design is done in a CAM system, but without electronic information, CAM is limited. I know that many mechanics say that they program CNC machines in the control system without a CAD system, but the blueprint for their work is probably made with a CAD system.
There may be 100 people who know what CAD is known for every 2 CAMs. In the same way, no CAD has no CAM, no CNC machinery and no CAM. A CNC machine is simply a computerized machine that relies on a series of commands or program instructions that include location information for accomplishing a particular task. This usually [but not always] uses a particular type of cutting tool for some sort of cutting motion.
Technically, this program code format is specified as RS-474, but most people refer to it as G and M code. Since FANUC is the most popular type of CNC control, the CNC code is often referred to as "FANUC compatible", which means standard G and M code.
CNC machine tools are not limited to typical CNC milling machines and CNC lathes that have been used for nearly 50 years in machine shops across the country. They come in a variety of shapes and sizes. Hundreds of dozens, grinders, turret punches, lasers, plasma, water jets, wire braids, shears, brakes, coordinate measuring machines, embroidery machines, welders, routers, fixture holes And robots can be used for most jobs. The type of CNC machine used in today's manufacturing.
I think of a sentence from the 17th century mathematician Gotfried von Leibniz, who once said: "It is not worthwhile to lose working hours like a slave in computing work. If you use a machine, you can safely downgrade to anyone else. He also strongly advocates Using a binary number system, this is the basis for modern computer numerical calculations.
CNC manufacturing technology is the inevitable result of the application of computer technology in manufacturing. It enables manufacturing to surpass the reliance on "excellent talent" to produce parts by hand.
CAD CAM and CNC technology produce parts and assemblies with the speed and precision that a generation has always dreamed of. The complexity of modern manufacturing parts has not been possible in previous generations. Although these industries require the same level of skill, as in the early days, the limitations of manual methods and the inherent inefficiencies have been largely overcome.
