9.1.1 Outline of ATC Control

The ATC (Automatic Tool Change) can be controlled in the following two ways:
 Mechanical random control
With the information of magazine position from the machine, and T command, the control method determines the direction of
magazine rotation, number of steps, etc. for index of the magazine, according to the given command.
Each tool and magazine tool pot (socket) have a one-on-one corresponding relation.
Usually, the "intermediate pot" that supports the transfer of the tool is provided between the spindle and the magazine.
This control is possible by not using ATC instruction, but ROT instruction only.
 Memory random control
With the information of magazine rotation, or magazine position from the machine, the control method controls tool No. stored
in the memory. For index of the magazine, the direction of magazine rotation and number of steps, etc., are determined by the
given T command and tool No. stored in the memory. Each tool and magazine tool pot (socket) does not always have a one-
on-one corresponding relation.
Usually, the "intermediate pot" is not provided.
