Question:

How does the tool radius compensation of the machining center determine positive and negative

How does the tool radius compensation of the machining center determine positive and negative

Answer:

G41 is relative to the tool forward direction of the left side of the compensation, known as the left knife fill.
Use the tool compensation function can be programmed without considering the radius of the tool, directly according to the size of the pattern to be programmed, as long as the actual processing of the input tool radius value can be.
