Working without radius compensation e. During datum setting you set the TNC display to the coordinates of a known position on the workpiece:.

Insert a zero tool with known radius. Touch the reference surface in the working plane with the tool and enter the position of the tool center. P S lies outside of the contour and must be approached without radius. P H lies outside of the contour and is calculated by the TNC. The tool moves from the starting point P S to the auxiliary point. First contour point P A and last contour point P E. P N lies outside of the contour and results from the DEP departure.

Contour Approach and Departure. Path Functions. Regardless of whether the tool or the workpiece is actually moving, you always program as if the tool is moving and the workpiece is stationary.

Target positions can be entered in Cartesian or polar coordinates — either as absolute or incremental values, or with both absolute and incremental values in the same block.

Before you execute a part program, always pre-position the tool to prevent the possibility of damaging the tool or workpiece!

P N T Texts as. Fundamentals 5. Fundamentals 6. You can also use the touch probe in the Manual and Electronic Handwheel operating modes to make simple measurements on the workpiece. With a 3-D touch probe you can determine:. Select the probe direction and axis of the coordinate. Use the corresponding soft keys for selection. The TNC displays the coordinates of the probed corner as datum. If you will need the current datum later, write down the value that appears in the datum display.

Select the probe direction with the soft keys: Same axis but from the opposite direction. The value displayed as datum is the distance between the two points on the coordinate axis. You can use the 3-D touch probe to measure angles in the working plane. You can measure. Rotation angle: If you will need the current basic rotation later, write down the value that appears under Rotation angle.

This is done by setting the rotation angle to the value that you wrote down previously. Probe the second side as for a basic rotation, but do not set the rotation angle to zero! Cancel the basic rotation, or restore the previous basic rotation by setting the rotation angle to the value that you wrote down previously.

The TNC provides five cycles that enable you to measure and compensate workpiece misalignment. In addition, you can reset a basic rotation with Cycle Compensation via basic rotation. Compensation via table rotation. For the cycles , and you can define through parameter Q Default setting for basic rotation whether the measurement result is to be corrected by a known angle a see figure at right.

Touch probe cycle determines a workpiece misalignment by measuring two points, which must lie on a straight surface. The TNC offsets the touch probe by the safety clearance in the direction opposite the defined traverse direction.

Before a cycle definition you must have programmed a tool call to define the touch probe axis. First measuring point in the 1st axis Q absolute : coordinate of the first touch point in the reference axis of the working plane. First measuring point in the 2nd axis Q absolute : coordinate of the first touch point in the minor axis of the working plane.

Second measuring point in the 1st axis Q absolute : coordinate of the second touch point in the reference axis of the working plane. Second measuring point in the 2nd axis Q absolute : coordinate of the second touch point in the minor axis of the working plane. Measuring axis Q axis in the working plane in which the measurement is to be made:.

Traverse direction 1 Q direction in which the probe is to approach the workpiece:. Setup clearance Q incremental : additional distance between measuring point and ball tip. Q is added to MP Clearance height Q absolute : coordinate in the touch probe axis at which no collision between tool and workpiece fixtures can occur.

Traversing to clearance height Q definition of how the touch probe is to move between the measuring points:. Default setting for basic rotation Q absolute : If the misalignment is to be measured against a straight line other than the reference axis, enter the angle of this reference line.

The TNC will then calculate the difference between the measured value and the angle of the reference line for the basic rotation. The touch probe cycle measures the centers of two holes. Then the TNC calculates the angle between the reference axis in the working plane and the line connecting the two hole centers. First hole: Center in 1st axis Q absolute : center of the first hole in the reference axis of the working plane.

First hole: Center in 2nd axis Q absolute : center of the first hole in the minor axis of the working plane. Second hole: Center in 1st axis Q absolute : center of the second hole in the reference axis of the working plane.

Second hole: Center in 2nd axis Q absolute : center of the second hole in the minor axis of the working plane. The touch probe cycle measures the centers of two studs. Then the TNC calculates the angle between the reference axis in the working plane and the line connecting the two stud centers. First stud: Center in 1st axis Q absolute : center of the first stud in the reference axis of the working plane. First stud: Center in 2nd axis Q absolute : center of the first stud in the minor axis of the working plane.

Diameter of stud 1 Q approximate diameter of the 1st stud. Enter a value that is more likely to be too large than too small. Second stud: Center in 1st axis Q absolute : center of the second stud in the reference axis of the working plane. Second stud: Center in 2nd axis Q absolute : center of the second stud in the minor axis of the working plane. Diameter of stud 2 Q approximate diameter of the 2nd stud.

The workpiece can be clamped in any position on the rotary table. Measuring axis Q axis in which the measurement is to be made:. Axis for compensation motion Q assignment of the rotary axis in which the TNC is to compensate the measured misalignment:. Welcome to ManualMachine.

TNC functions that may not be available on your machine include: Digitizing option Tool Measurement with the TT Please contact your machine tool builder to become familiar with the features of your machine. Location of use The TNC complies with the limits for a Class A device in accordance with the specifications in EN , and is intended for use primarily in industrially-zoned areas.

If you are working alternately with a triggering and a measuring touch probe, be sure that You have selected the correct touch probe in MP The TNC cannot detect which probe is actually in the spindle.

Function Whenever the TNC runs a touch probe cycle, the 3-D touch probe approaches the workpiece in one linear axis. Y When the probe stylus contacts the workpiece, the 3-D touch probe transmits a signal to the TNC: the coordinates of the probed position are stored, the touch probe stops moving, and returns to its starting position in rapid traverse.

Touch Probe Cycles in the Manual and Electronic Handwheel Modes In the Manual and Electronic Handwheel operating modes, the TNC provides touch probe cycles that allow you to: Calibrate the touch probe Compensate workpiece misalignment Datum setting Touch probe cycles for automatic operation Besides the touch probe cycles, which you can use in the Manual and Electronic handwheel operating modes, the TNC provides numerous cycles for a wide variety of applications in automatic operation: Calibrating the touch probe Chapter 3 Compensating workpiece misalignment Chapter 3 Setting datums Chapter 3 Automatic workpiece inspection Chapter 3 Automatic workpiece measurement Chapter 4 Digitizing with triggering or measuring touch probe Option, Chapter 5 You can program the touch probe cycles in the Programming and Editing operating mode via the TOUCH PROBE key.

To improve clarity, the help illustrations sometimes omit certain parameters. Defining the touch probe cycle in the Programming and Editing operation mode The soft-key row shows all available touch probe functions divided into groups.

The TNC ends the dialog when all required data has been entered. Group of measuring cycles Soft key Cycles for automatic measurement and compensation of workpiece misalignment Cycles for automatic datum setting Cycles for automatic workpiece inspection Automatic calibration cycle Cycles for digitizing with measuring touch probe option, not available for ISO Cycles for digitizing with measuring touch probe option, not available for ISO Cycles for automatic tool measurement enabled by the machine tool builder, not ISO.

To make it possible to cover the widest possible range of applications, machine parameters enable you to determine the behavior common to all touch probe cycles: Maximum traverse to touch point: MP If the stylus is not deflected within the path defined in MP, the TNC outputs an error message. Safety clearance to touch point: MP In MP you define how far from the defined or calculated touch point the TNC is to pre-position the touch probe. Multiple measurement: MP To increase measuring certainty, the TNC can run each probing process up to three times in sequence.

Confidence interval for multiple measurement: MP In MP you store the value by which the results may differ when you make multiple measurements. Touch trigger probe, rapid traverse for prepositioning: MP In MP you define the feed rate at which the TNC pre-positions the touch probe, or positions it between measuring points. Measuring touch probe, rapid traverse for prepositioning: MP In MP you define the feed rate at which the TNC pre-positions the touch probe, or positions it between measuring points.

Running touch probe cycles All touch probe cycles are DEF active. NC software Touch probe cycles with a number greater than position the touch probe according to a positioning logic: If the current coordinate of the south pole of the stylus is less than the coordinate of the clearance height defined in the cycle , the TNC retracts the touch probe in the probe axis to the clearance height and then positions it in the working plane to the first starting position.

A file must not be active in the Programming and Editing mode of operation. Writing the measured values from probe cycles in datum tables This function is active only if you have datum tables active on your TNC bit 3 in machine parameter Enter the name of the datum table complete path in the datum table input box. Enter the tool axis with the axis key.

Datum: Enter the height of the ring gauge. The menu items Effective ball radius and Effective length do not require input. Move the touch probe to a position just above the ring gauge.

Calibrating the effective radius and compensating center misalignment After the touch probe is inserted it normally needs to be aligned exactly with the spindle axis. Select the tool axis and enter the radius of the ring gauge. Displaying calibration values The TNC stores the effective length and radius, as well as the center misalignment, for use when the touch probe is needed again.

Storing calibration values in the TOOL. Managing more than one block of calibrating data as of NC software xx To be able to use more than one block of calibration data, you must set bit one in machine parameter To select the 3-D calibration cycle, press the 3D CAL soft key Enter the values for stylus radius 1 and stylus radius 2. Diameter ring gauge: The diameter is engraved on the standard ring gauge.

Displaying calibration values The compensation factors and force ratios are stored in the TNC for later use whenever the measuring touch probe is needed. Position the ball tip at a starting position near the first touch point. Position the ball tip at a starting position near the second touch point. Enter a rotation angle of zero and confirm with the ENT key. To terminate the probe function, press the END key. Probe 2. Move the touch probe to a starting position near the touch point.
