M-Code M06 Automatic Tool Changer code
M06 (Tool Change Command) and Pre Tool:
M06 is the M-code Used in the CNC Program
to activate the automatic tool change along which T number called on the
program. As soon as the controller reads the T number with M06 it will search
the Tool magazine for the T number specified and rotates and brings the tool
into the spindle.
Example:
T02 M06,
this Command activate the controller to change the tool to T02, so the
controller searches the Tool magazine for tool number 2 and it rotates to the
tool change position and then it takes up the Tool number 2 into the spindle.
Pre-tool:
In
Modern CNC Tool machines to save the time pre-tool can be called and kept ready
for next tool change in the magazine. As soon as the controlled reads the next
block of Tool change, the T number given in program will be detected by the
controller and reads the tool number on the magazine to prepare the tool and
kept in position of tool change while the current tool is in cutting progress.
Examples:
N170 T02 M06 (Automatic Tool change to Number
2)
N171 T03 (Pre-tool
to keep ready in magazine for next)
N172 G54 G90 G00 X10 Y10 Z50 (Origins and
