： Machining Center Standard Training Part Two (NC Code)
NC stands for numerical control and is the most commonly used method for executing machining operations on computer controlled machines. Its purpose is to generate a set of instructions for the machine tool, which it interprets and executes. NC commands are written in Rapid programs and consist of words, numbers, and symbols.
In order to understand and control the machine, the user must have knowledge of the machine and the functions. This includes the ability to understand and interpret NC code, which is the basic language of a modern CNC machine. The NC code indicates the type of actions to be performed and controls the motion and speed of each operation.
NC code consists of a set of commands as well as a variety of parameters. The commands in the code tell the machine what to do in terms of motion, spindle speed and orientation, tool selection, and other related functions. Some of the more commonly used commands are:
G00 - rapid positioning
G01 - linear interpolation
G02 - circular interpolation
G03 - contour interpolation
G04 - dwell
G05 - fixed cycle
G06 - move in linear trajectory
The parameters associated with the commands provide additional details about the sequence of operations and the machine’s behavior. Examples of parameters include the feed rate, spindle speed, and program stop for dimensional accuracy.
In order to produce parts using a CNC machine, the programmer must understand how to interpret and write NC code to run the machine. This includes understanding how the code relates to the instructions that the machine must carry out, as well as the specific instructions and parameters associated with each command.
It is important to have good programming practices in order to get the most out of the CNC machine. Programming correct and efficient NC code requires extensive experience and understanding of the machine language. To ensure that the code runs properly and that the parts are machined accurately and to specification, it is also important to practice good program and tool management.
Every user of a CNC machine must be familiar with the main components of NC code and understand how to interpret it. By doing so, they can get the most out of their CNC machines and produce parts that are of the highest quality and accuracy. NC code is the basis for creating a machined part and will affect the success of the operation.
