Understanding the Computer Numerical Control Machine as well as learning the method of programming these machines is not enough to maximize the capability of these devices. Even if you are proficient on those two stated above, proper understanding of the step by step procedures is still important.



In this article we would talk about the step by step procedures of programming Computer Numerical Control Machines which is recommended by the most experienced CNC Machine Operators and progammers.



Step by Step procedures in planning of a CNC program



Whenever we try to program a Computer Numerical Control Machine the first thing that the Machine operator should consider is the blueprint of the part we are trying to manufacture. Proper understanding and reading of a blueprint is a basic and the most important skill in the manufacturing Industry that engineers, managers, CNC machine operators as well as CNC programmers should know about.



Proper understanding of these blueprints should help the CNC machine operator as well as the programmer to use the appropriate CNC machine to be used.



The second step on the proper programming of a Computer Numerical Control Machine is by selecting the appropriate type of Machine that will be used. This is where the proper understanding of each machine type comes into play. Knowing the type of design, specifications as well as features of a machine will help you on choosing the appropriate one.



The third step would be the analysis of the operations or the setup sheet. The setup sheet is used to describe the necessary processes needed to create the parts on a CNC machine. The setup sheet includes the proper machine sequence and also the tools and cutting data to be used. Specifications written on the setup sheet aids the programmer on the proper algorithm needed by the Computer Numerical Control Machine.



The fourth step on the step by step requirements would be the proper selection of the tools required to create the parts. This step is important on the industry manufacturing practices, basically the tools to be chosen is based on the common sense and Good CNC operators and programmers should be aware of them. Usually there is a certain checklist on this step, the most important point of this checklist would be knowing the material to be machined as well as its characteristics.



Fifth step would be the calculation of the cutting data. Proper calculation is one of the important steps in the planning process. This is where the spindle speed, federate value, cutting speed and the depth of cut is calculated to fit to the specifications in the blueprint.



Sixth step would be the actual programming process, this is also the step where the proper Units are inserted into the programming algorithm of the Computer Numerical Control Machine. This is where we incorporate all the codes that are needed to run the whole CNC machines in the CAD software.



Programming Considerations



In order for other programmers to analyze and append your algorithm, it is important to have certain programming considerations. These program considerations were suggested by experienced Computer Numerical Control Machine Programmers and Operators.



First it is important that you develop a programming technique that will be readily understood by other developers, with a good programming technique programs could easily be appended if there are any errors.



Second, it is also important to proofread all programs for typographical errors before being executed in the CAM software, this is to ensure that the CNC machine would operate its desired operation. And most important of all is to keep your programs as simple as possible in order for the machine to process the instructions faster.
