Cycle 441 FAST PROBING (#17 / #1-05-1)
ISO programming
G441
Application
Program interruption Q400=1
Parameter Q400 INTERRUPTION allows interrupting the cycle run and displaying the obtained results.
Program interruption by Q400 is effective in the following touch probe cycles:
- Touch probe cycles for checking the workpiece: 421 to 427, 430 and 431
- Cycle 444 PROBING IN 3-D
- Touch probe cycles for measuring the kinematics: 45x
- Touch probe cycles for calibrating: 46x
- Touch probe cycles 14xx
Cycles 421 to 427, 430 and 431:
The control displays the results obtained during a program interruption in a FN 16 monitor output.
Cycles 444, 45x, 46x, 14xx:
The control automatically shows the results obtained during a program interruption in an HTML log in the path: TNC:\TCHPRlast.html. You can open the HTML log in the Document workspace.
Notes
- This cycle can only be executed in the FUNCTION MODE MILL machining mode.
- END PGM, M2, M30 reset the global settings of Cycle 441.
- Cycle parameter Q399 depends on your machine configuration. Your machine manufacturer is responsible for the setting of whether the touch probe can be oriented through an NC program.
- Even if your machine has separate potentiometers for rapid traverse and feed rate, you can control the feed rate with the feed rate potentiometer only, even with Q397=1.
- If Q371 is unequal to 0 and the stylus does not move in cycles 14xx, the control will terminate the cycle. The control returns the touch probe to the clearance height and saves the workpiece status 3 in Q parameter Q183. The NC program continues.
Workpiece status 3: Stylus does not move
Note regarding machine parameters
- The machine parameter maxTouchFeed (no. 122602) allows the machine manufacturer to limit the feed rate. You define the maximum absolute feed rate in this machine parameter.
Cycle parameters
Help graphic | Parameter |
---|---|
Q396 Positioning feed rate? Define the feed rate at which the touch probe will be moved to the specified positions. Input: 0...99999.999 | |
Q397 Pre-pos. at machine's rapid? Define whether the control, when prepositioning the touch probe, traverses at FMAX feed rate (machine's rapid traverse): 0: Pre-position at the feed rate from Q396 1: Pre-position at the machine's rapid traverse FMAX Input: 0, 1 | |
Q399 Angle tracking (0/1)? Define whether the control will orient the touch probe before every probing operation: 0: Do not orient the spindle 1: Orient the spindle before every probing operation (increased accuracy)? Input: 0, 1 | |
Q400 Automatic interruption? Define whether the control will interrupt program run and output the measurement results on the screen following a touch probe cycle: 0: Do not interrupt program run even if, in the specific touch probe cycle, the output of measurement results on the screen is selected 1: Interrupt program run and output measurement results on the screen. You can then resume the NC program run with NC Start. Input: 0, 1 | |
Q371 Touch point not reached? Define how the control behaves when the stylus does not move within the DIST value of the touch probe table. 0: The control interrupts the NC program with an error message saying that the touch point cannot be reached. This is standard behavior. 1: The control displays a warning and terminates the probing cycle. The NC program continues. Is effective only in the 14xx cycles. 2: The control displays no warning and terminates the probing cycle. The NC program continues. Is effective only in the 14xx cycles. Input: 0, 1, 2 |
