Planning Computer Numerical Control
Programs
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.
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.
