Which G-code corresponds to Tool Radius Compensation in Position 1?

The G-code related to Tool Radius Compensation in Position 1 is G41. This code instructs the CNC machine to compensate for the tool's radius when machining. Specifically, using G41 indicates that the tool path should be adjusted to the left of the programmed path, which accounts for the offset essentially caused by the tool’s radius.

In practice, this means that when a programmed path is defined, the machine understands that the actual cutting will occur to the left side of this path, thereby ensuring accuracy and precision in machining operations. The use of G41 is essential in applications where tolerances are tight and the geometry of the part being machined requires fine adjustments based on the size of the tool.

Other codes, such as G40, G42, and G28, serve different functions within the CNC programming context. G40 cancels any tool radius compensation that may have been previously set, G42 is used for compensation to the right of the programmed path, and G28 is utilized for returning the machine to the home position. Understanding these distinctions is vital for programmers to ensure they utilize the correct settings for effective machining.
