Fig 4-8: tool cutter compensation In control programs, a number following address G determines the meaning of the command for the concerned block. G code list is shown in Table 4-2. G codes are divided into the following two types: 1) One-shot G code. The G code is effective only in the block in which it is specifed. 2) Modal G code.
