After the protected beginning segment of the program is set up, the ideal instrument should be stacked in the axle utilizing the ATC. This errand is finished by utilizing a mix of a下-and M-word in a solitary square to play out an instrument change. A M6 and T-word determining the ideal device number orders the ATC to stack the device in the shaft. For instance, M6 T1 will make the ATC consequently load device #1 in the axle. The device change is acted in fast movement naturally. Observe that some machine controls require the M6 and T-word to be in a particular request. On the off chance that the shaft is running when an instrument change is directed, most machines will naturally stop the axle before the device change, 5o no M5 code is required.
It is significant that the instrument can dump and load apparatuses in a protected spot clear of crashes. It is here and there best to move the machine tomahawks to their home situation for instrument changes. This is typically the most secure area. Programming a G91 with a G28 makes situating happen comparative with the machine home situation, rather than the work facilitate framework. Following a G91 G28 with a Z0. Will move the Z-pivot up to the Z-home position. Continuously move the Z-pivot first in a square without help from anyone else, so it is clear of any impediments during the X-and Y-tomahawks move. The following square will play out a different XY move to home. At that point the following square orders the apparatus change. Squares for a fast move to this protected machine home position and device change resemble this:
G91 G28 Z0. (Quick TO MACHINE Z-HOME FOR TOOL CHANGE);
G91 G28 X0. Y0. (Quick TO MACHINE XY-HOME FOR TOOL CHANGE);
M6____ (CHANGE TOOL);
Program Stop Commands
One of two diverse M-codes can cause a program stop, or hold, on the program until it is continued by squeezing the cycle start button. These are frequently embedded preceding or after device changes to permit examination of a device or to check the outcomes delivered by a finished activity.
A MO order is a full stop and consistently requires the administrator to restart the program by squeezing the cycle start button on the administrator board. This can be utilized when a section should be repositioned, chips should be cleared, or to check a basic measurement prior to proceeding. A M1 order is a discretionary stop. A switch on the administrator board should be turned on for the machine to peruse this discretionary pause and interruption the program. A discretionary stop may likewise be utilized to stop the cycle before another activity starts. It is regularly utilized when running another program interestingly so investigations can be performed. After the program is demonstrated protected and right, the discretionary stop switch can be killed and the program will disregard the M1 order.
A few machines get back to the default WCS of G54 when the ” RESET” button on the control board is squeezed to drop a running project. After that reset, whenever wanted, a program might be restarted at an instrument change block. Hence, it is acceptable practice to put the ideal WCS code after each instrument change to guarantee the right work balance is actuated.
The full stop or discretionary stop ought to be a solitary square of code. A discretionary stop before an apparatus change and a reactivation of the ideal WCS would resemble this:
M1(OPTIONAL STOP);
M6 T1 (CHANGE TOOL);
G54 (SET WCS 1);
On the off chance that a full stop is wanted, the accompanying code would be utilized. Notice the remark giving the administrator significant guidelines:
MO (PROGRAM STOP-FLIP PART);
M6T___ (CHANGE TOOL);
G54 (SET WCS 1);
