Pseudo-code is a type of programming language that uses plain language to outline the logic and structure of a program without being tied to any specific programming language. Pseudo code is typically less detailed than actual code, and may not include specifics such as syntax or variable names.

• Pseudo-code is important because it allows programmers to plan and design the structure of a program before writing actual code, which helps identify potential issues or problems early in the development process.

In the context of G-code programming for CNC machining, pseudo-code can be used to plan and design the tool path for a part before writing the actual program in the G-code programming language. Once the pseudo-code is complete, the programmer can then use it as a guide to write the actual G-code program.

• This can help to ensure that the toolpaths are optimized for the part and that the machining process will be efficient and accurate.

Code Documentation is a process of creating documentation, often in the form of written text, diagrams, or comments in the code itself, that explains how a particular software program or system works. The purpose of code documentation is to help other operators/programmers/engineers understand the code, use it effectively, and maintain it over time. Code documentation typically includes information such as:

• How the different parts of the code are organized and interact with each other

• Any special considerations or limitations that must be taken into account when using the code

• Any assumptions or requirements that must be met for the code to work correctly

• The purpose and functionality of each command within the code

While pseudo-code can be used to outline the program's logic and function, documentation is used to outline the processes related to the program, such as:

• Machine setup instructions

  • Part/Stock setup instructions

  • WCS locating instructions

  • Tool setup instructions

• In-process operation instructions

  • Part/feature inspection

  • Part reorientation between operations

Both Pseudo-Code and Documentation can be practically accomplished through the use of Comments within the G-Code program itself

• Comments are not executable/readable by machines, and exist exclusively for the operator, programmer, and engineer's sake

  • This also means that the comment is not subject to the same G-Code "rules" - particularly with respect to syntax - and can include most characters and symbols

• For CNC machines, Comments are indicated several ways, one of the most common being anything within a set of parentheses, e.g.: (Comment)

When adding advanced functionality to G-Code to automate processes, it requires a fundamental shift in how you might typically interact with G-Code:
