Programming CNC Machines With G-Codes

Ever since the industrial revolution started, the demand to create precise instruments and products is an important factor in large scale manufacturing. Belts, screws, Drills and all movable parts needed to create other products in the assembly line must all be exact and compatible, thus extra care must be taken in order to ensure that all moving parts match perfectly. Computer Numerical Controlled programming has become an extremely important part of this process.

Computer Numerical Controlled Machines are useless without any programming. CNC’s rely on pure hard codes in order to execute commands that the Machine Operator wants to do, therefore not only is it needed to learn the mechanics of the whole Computer Numerical Controlled Machine but it is also at the utmost importance that the Machine operator knows how to communicate with the machine, and that is by using G-codes.

Preparatory code/ functions or much commonly called as G-codes are functions in the Computer Numerical Control programming language. The G-codes job is to manage the position of the tool as well as control the step by step commands during the actual work. Basically the G-codes are the most important part of the Computer Numerical Control Programming algorithm.

There are other codes involved in the programming of CNC’s such as M-codes that manages the machine, T-codes for managing the tools, and F-codes for the tool feed and tool speed controls. All of these codes are created in a Computer Aided Manufacturing (CAM) software.

G codes as well as the others use the RS-274D as the recommended standard for the Computer Numerical Controlled Machines. This standard was developed by the Electronic Industry association during the 1960’s. These standards provide a basis for the creation of Computer Numerical Controlled Programs.

First designs of these standards came from punched paper tapes as the medium standard for data interchange, but now ASCII character bit patterns are the standard for the representation.

G-Codes

Lets discuss the g-codes further, as what I have said earlier G- codes constitute only a part of the Computer Numerical Control Program, in the whole programming algorithm, they are denoted by the letter G, Basically it is a code telling the machine what kinds of actions to perform in a step by step basis, examples of these actions would be rapid move, controlled feed moves that would bore holes, a work piece cut routed to a specific dimension, change a pallet, and set a tool information such as offset.

After creating each part of the codes, the algorithm is compiled in the Computer Aided Manufacturing (CAM) software. The CAM software basically use translators called post processors to output the code optimized for a certain machine type. Often times, post-processors are often used to allow users to enable further customization.

G-codes can also be used to create outputs for Computer Aided Design systems used to design printed circuit boards (PCB). Any software must be customized for each type of machine tool that it will be used to program. Some G-codes are written by hand for volume production jobs.

Some Computer Numerical Controlled machines use conversational programming. Conversational programming is an easier way to program CNC machines because it is more “user friendly” because it uses a wizard like program that hides the G-codes into plain view. Some Popular examples of this kind of CNC machines are the Southwestern Industries’ Proto TRAK, Mazak’s Mazatrol, and Mori Seiki’s CAPS conversational software.

Conclusion

With these kinds of further sophistication in programming Computer Numerical Controlled Machines, it is expected in the future that programming would be much easier for its machine operators.

The Importance Of Mastercam Software In The Manufacturing Industry

Mastercam software is one of the most important breakthroughs in manufacturing technology. Together with CAD software, they are collectively referred to as CAD/CAM. CAD/CAM is an acronym that stands for Computer Aided Design and Computer Aided Manufacture. With these special programs, engineers, architects and designers can use computers to design products and structures with relative ease. Using Mastercam software, engineers and machinists can use the digital information created using CAD software to manufacture products and parts accurately in a timely manner.

The first CAD/CAM software was introduced back in the year 1983 and the technology has steadily been improving since then. Professionals from different industries can use these programs to create modern conveniences like machines and structures that make our way of life possible. The industries that benefit from these tools include the construction industry, the manufacturing industry, the engineering industry, the architectural industry and many others. Computer Aided Design software allows designers to create and design virtual blueprints of parts on a computer. These virtual blueprints contain important data like measurements and dimensions. On the other hand, Computer Aided

Manufacturing software like Mastercam software allows machinist to implement the virtual blueprints created using Computer Aided Design software during the manufacturing process. Computer controlled machines use the data from these blueprints to accurately manufacture parts that conform to the data from the CAD files. If you want to pursue a career in the modern manufacturing industry, then you will have to undergo Mastercam training. Only then will you be eligible to work with the expensive and complex machines that produce the things that make our way of life possible.

While there are many examples of CAD/CAM software out in the market today, Mastercam software is arguably the industry standard. This is partially because this software was created by one of the oldest and most trusted players in the development of CAD/CAM software. Mastercam software uses a large array of predefined toolpaths that can control processes like advanced multiaxis, surface high speed, engraving, peel mill, face, pocketing, drill and contour. This software was also designed from the ground up for use by engineers and machinists. Aside from the predefined toolpaths, machinists and engineers can also create their own toolpaths. This software is extremely versatile and an able professional who has undergone proper Mastercam training can accomplish a lot with it.

Aside from the features stated above, Mastercam software is also compatible with many third party applications that can be used to further extend its capabilities. These third party applications are referred to as C-hook and they may be used to create customized machine specifications for use in special situations.

In the world we live in, computers are playing a more important role. These days, we use computers for almost any task you can think of and the manufacturing industry is no exception. Mastercam software allows companies to manufacture products and parts at higher speeds and greater efficiency while maintaining high levels of quality, uniformity and consistency. Without CAD/CAM software, engineers and other professionals would be hard pressed to meet the growing demands of our increasingly technology-dependent society.
