Automatic Tool Presetter — Haas Automation
-
0:10 - 0:12In this video, we will show you how to use the
-
0:12 - 0:19automatic tool presetter option for Haas CNC turning centers
-
0:19 - 0:24The automatic tool presetter offers three modes of operation:
-
0:24 - 0:29Manual mode is used for initial setup of tool offsets
-
0:29 - 0:36Automatic mode is used to update offset values after a tool’s inserts have been changed
-
0:36 - 0:44And break detect mode is used to check the cutting face using a pre-set tolerance for tool wear
-
0:44 - 0:48To start, press the [MDI DNC] button
-
0:48 - 0:53and then Program Conversational [PRGRM CONVRS] to reach the tabbed menu
-
0:53 - 0:57Right cursor to the "Probe" tab and press [WRITE / ENTER]
-
0:57 - 1:01This brings up the "Probe" menu in manual mode
-
1:01 - 1:06This turret holds five tools that have no existing offset data
-
1:06 - 1:11Let’s start in Manual mode to generate the necessary data for each tool
-
1:11 - 1:16Check that "Manual" is selected in the "OP Mode" box
-
1:16 - 1:19The turret is at tool position number 12
-
1:19 - 1:22and therefore the "Tool Number" box reads "12"
-
1:22 - 1:26This box will always display the current turret tool position
-
1:26 - 1:30Enter the offset number you would like to use for this tool
-
1:30 - 1:32There are 50 offset numbers available
-
1:32 - 1:38but typically the offset number is set the same as the tool number
-
1:38 - 1:41Next, set the value for "Tool Tip Direction"
-
1:41 - 1:49based on the configuration of the tool you're setting
-
1:49 - 1:56In this case we are checking a turning insert with its tip in the number 2 direction
-
1:56 - 1:59We can’t enter a value in the "Tolerance" box
-
1:59 - 2:04since we only use that in Break Detect Mode
-
2:04 - 2:06With the turret a safe distance away
-
2:06 - 2:12move the probe arm into position by pressing [F1]
-
2:12 - 2:14With the data entered for tool number 12
-
2:14 - 2:17you’re ready to check the tool position
-
2:17 - 2:21Handle jog the tool in Z and X until it is approximately
-
2:21 - 2:24One quarter inch (0.25", 6.35mm) diagonally away from the edge of the probe
-
2:24 - 2:30Similar to the image displayed in the tool tip direction graphic
-
2:30 - 2:37If the operator door is open you will need to hold down [CYCLE START] to continue with the touch off cycle
-
2:37 - 2:41Or, with the door closed, press [CYCLE START]
-
2:41 - 2:48The tool tip will touch off in the Z and X directions and record the offsets
-
2:48 - 2:55Note that a G-code program is generated in "MDI" which is used for the tool movement
-
2:55 - 2:58With the first tool set, move the turret a safe distance
-
2:58 - 3:03from the probe arm, and index to the next tool
-
3:03 - 3:06Continue on to set the remaining offsets
-
3:06 - 3:09When you are finished setting the offsets for all your tools
-
3:09 - 3:17Don’t forget to press [F1] to bring the probe arm back to its resting position
-
3:17 - 3:21With the tools now set, you still need to define your work offset
-
3:21 - 3:25Start by selecting the desired Z work offset
-
3:25 - 3:28We are using G54
-
3:28 - 3:31Using any of the tools you’ve already probed
-
3:31 - 3:38touch the tool to the part face and press [Z FACE MEASURE]
-
3:38 - 3:47The distance from the tool probe to the face of the part is loaded in G54, and Z work zero is now set
-
3:47 - 3:50Once a tool offset has been set in "Manual" mode
-
3:50 - 3:54You can update the tool tip position at any time an insert is changed out
-
3:54 - 3:56Here is how:
-
3:56 - 4:02Access the "Probe" menu and select "Automatic" from the "OP Mode" box
-
4:02 - 4:06Arrow down to select the tool number you want to check
-
4:06 - 4:11With the tool number and offset selected, press [CYCLE START]
-
4:11 - 4:16The turret will index to the tool selected in the "Tool Number" box
-
4:16 - 4:24and bring the tool to the probe and check the offsets
-
4:24 - 4:30Repeat this automatic sequence for each tool that needs to be updated
-
4:30 - 4:33"Break Detect" mode allows you to measure the difference between
-
4:33 - 4:36the initial probe reading for a particular tool insert
-
4:36 - 4:41and subsequent readings after wear or damage may have occurred
-
4:41 - 4:44The tolerance setting in this mode establishes
-
4:44 - 4:48the allowable wear on a given cutting edge
-
4:48 - 4:51Select Op Mode "Break Detect"
-
4:51 - 4:54and the tool number and offset number you used
-
4:54 - 4:58Now select a tolerance for wear on this particular insert
-
4:58 - 5:04In this example, we have set this value to 0.004" (0.1016mm)
-
5:04 - 5:07When the operator presses [CYCLE START] the turret will index
-
5:07 - 5:10to the tool we have entered in the Tool Number box
-
5:10 - 5:16and the turret will move to the probe and check the insert
-
5:16 - 5:21If the insert is not within the tolerance set earlier, an alarm will announce
-
5:21 - 5:26that you have a cutting edge that is no longer within specification
-
5:26 - 5:31When you run break detect mode, a program is generated in "MDI"
-
5:31 - 5:35If you paste this into a part program in memory, you will have added
-
5:35 - 5:38that particular break detect routine to a your program so that
-
5:38 - 5:42critical tools are measured before they are used
-
5:42 - 5:45The "Break Detect" routine is automatically generated
-
5:45 - 5:47in the upper left side of the "MDI" screen
-
5:47 - 5:51and is ready to be pasted into a part program
-
5:51 - 5:57To insert this sub-routine into a part program, start by pressing [F4]
-
5:57 - 6:02Choose number one, “Select / Create Program”
-
6:02 - 6:09Find the program you want to modify
-
6:09 - 6:14Now, simply scroll to the area of the G-code where you want to insert the sub-routine
-
6:14 - 6:20And press [WRITE / ENTER]
-
6:25 - 6:28Here is a quick demonstration of the break detect routine
-
6:28 - 6:32running within our existing part program
-
6:32 - 6:35The part program is just ending a drilling operation
-
6:35 - 6:38Before continuing to a tight tolerance boring operation
-
6:38 - 6:41the machine will now automatically check
-
6:41 - 6:44that the next tool's insert is within size tolerance
-
6:44 - 6:50This is particularly useful for checking tools before critical operations
-
6:50 - 6:53With these three probing modes at your disposal
-
6:53 - 6:58Inputting and checking tool offsets and checking for excessive tool wear
-
6:58 - 7:04Making good parts should get significantly easier
