Selection of tool used for various machining - Tool Function (See i-1 0)
/Tool number
ATC magazine
When drilling, tapping, boring, milling or the like, is performed, it is necessary
to select a suitable tool. When a number is assigned to each tool and the
number is specified in the program, the NC selects the corresponding tool.
For example, when No.01 is assigned to a drilling tool and the tool is stored at
No.01 of the ATC magazine, the tool can be selected by specifying:TOI
This function is called the tool function.

Command for machine operations -
Miscellaneous function (See I-1 1)
When machining is actually started, it is necessary to rotate the spindle, and
feed coolant. For this purpose,on-off operations of spindle motor and coolant
valve should be controlled.
The function of specifying the on-off operations of the components of the
machine is called the miscellaneous function.
In general, the function is
specified by an M code.
For example, when MO3 is specified, the spindle is rotated clockwise at the
specified spindle speed.
(6)
Program configuration (See l-1 2)
A group of commands given to the CNC for operating the machine is called the
program.
By specifying the commands, the tool is moved along a straight line
or an arc, or the spindle motor is turned on and off.
In the program, specify the commands in the sequence of actual tool
movements.
