The Instruction function refers to a capability of CNC systems that allows users to program and instruct the machine tool by manually guiding its movements. With the teaching function, an operator can physically move the machine tool through a series of desired positions and record these movements as a program. The machine tool then memorizes and reproduces these actions precisely.
During the teaching process, the machine tool's movements are typically controlled in a manual or jog mode, where the operator can use handwheels, joysticks, or other control interfaces to guide the machine's motion. As the operator moves the machine tool to various positions, the system records the corresponding coordinates and creates a program that represents the desired tool path.
The teaching function is beneficial in scenarios where the machining process involves complex or irregular shapes that are challenging to program using traditional methods. By physically demonstrating the desired tool path, operators can easily create programs without extensive knowledge of programming languages or complex CAD/CAM software.
Once the teaching process is complete, the generated program can be stored, edited, and reused for subsequent machining operations, providing a practical and efficient way to program CNC machines.
