  • Page 22: Calculating The Calibration Of The Level Vials - Roll Axis

    Calculating the Calibration of the Level Vials – Roll Axis Note: It is very important to warm up the laser for at least 30 minutes before starting this procedure. It is also very important to level both the Pitch and Roll axis level vials during this procedure. Failure to do this makes it nearly impossible to calibrate the levels.
  • Page 23 5. Calculate the Set Point – Roll Axis Set Point = (Reading 1 + Reading 2) / Subtract the Set Point from Reading 1 and divide the result by the D1 (distance between the points). The result is the calibration of the level vial in units of in/ft or mm/m.

    4. Move the target to Far Position B and tilt the Pitch Axis of the laser until the readout reads zero. Be sure to use only Pitch Axis adjustment knobs that face the target when tilting the laser beam (in the setup displayed in Figure 18, this would be the PITCH adjustment).

  • Page 32: 2-Point Buck-In On Machine Tool Axis (Straightness)

    2-Point Buck-In on Machine Tool Axis (Straightness) A laser beam is often used as a "straight edge" to measure straightness. Examples are machine tool ways or bore straightness measurement. The laser beam must be adjusted to be parallel to or coincident with an edge or centerline.
  • Page 33 4. Return the column to its starting position and rotate the target toward the laser. Zero the target. 5. Send the column back to the far end of travel and tweak the Yaw-Axis adjustment knob to zero the laser. 6. When the target reads zero at both ends, the laser is aligned to the X-Axis.

  • Page 34: Measuring A Machining Center

    Measuring a Machining Center The following section describes how the laser is used to measure straightness, flatness, squareness, levelness and parallelism on a 6- axis horizontal floor mill. Note that if a machine is going to be aligned, rather than just measured, it is important to put the laser on an instrument stand.

  • Page 35: Procedure

    Procedure 1. Place the laser on the table at a spot that provides the ability to measure all the axes from the same setup. 2. Level the Pitch-Axis level via by using the coarse and fine adjustments to line up the edges of the bubble. Repeat the process with the Roll-Axis level vial.
  • Page 36 4. Turn on the laser rotation (which also turns on the targets). Target #1 data displays in the Read9 software on the PDA. Zero the display. Remove Target #1 and replace it with Target #2. Zero the Read9 display for Target #2. Repeat the process for Target #3.

  • Page 37: Aligning The Laser To The X-Axis Travel

    Aligning the Laser to the X-Axis Travel 1. Mount Target #4 on the ram, move the spindle and adjust the target height. 2. Power on the laser and zero the target in the Read9 PDA. Move the column down to the end of the X-Axis travel and rotate the target head to point towards the laser.

  • Page 38: Measuring X-Axis Straightness And Flatness Simultaneously

    Measuring X-Axis Straightness and Flatness Simultaneously The straightness and flatness for X can be measured simultaneously by adding a second measuring target to the bottom of the spindle ram. The targets come with a 3-piece post set, so a shorter post may be used to adjust the target height to pick up the red laser.

  • Page 39: Y-Axis Flatness And Straightness And Y-Z / Y-X Squareness

    Y-Axis Flatness and Straightness and Y-Z / Y-X Squareness After measuring the Y-Axis flatness and straightness, the Machine Geometry software calculates the Y-Z and Y-X Squareness. The Gold Plane (bottom left) measures Y Flatness and the Green Plane (bottom right) measures Y Straightness. 1.
  • Page 40 3. Move the column, pause a few seconds, and click Record. Repeat for each point. 4. The Gold Plane measures the squareness of the Y-Axis to Z and the Green Plane measures Y to X squareness. As before, the Machine Tool Geometry software does the straightness and squareness calculations.

    W-Axis Flatness and Straightness, W-Z (in X) Parallelism, W-Z (in Y) Parallelism Without changing the L-743 setup, the W-Axis can be measured for flatness and straightness and parallelism to the Z-Axis in the Y direction, and the parallelism to the Z-Axis in the X direction. 1.
  • Page 42 3. The red plane measures the flatness of W, W-Y squareness and parallelism to Z (in Y). The software records the straightness of W and calculates the squareness and parallelism to the other axes. The results show .0003 in. for straightness and .0011 in.

  • Page 45: Additional Capabilities Of The L-743 Machine Tool Alignment System

    6. For Z squareness to X and Y, the Machine Tool Geometry program subtracts the Best-Fit slope of Z from the Best- Fit slopes of Y and X and calculates the squareness. Therefore, the result for the squareness of Z to X is .0002 in/ft, which means the Z-Axis is tilting to the left.

To measure the A rotation, use the gold laser plane and a target mounted on the spindle. For both the A-axis and the Tram measurements, a simple tram bar can be inserted into the spindle with a target attached.
  • Page 49 4. Rotate to 90 degrees and zero the target. 5. Rotate to 270 degrees. This reading is -.0023, which means the A rotation axis is tilting toward the X-axis by .0023 in 18 in. Note: In Steps 3 and 5, the purple ellipse represents the measured plane.

  • Page 50: Tramming The Spindle

    Tramming the Spindle 1. To measure the “tram” (squareness of the A spindle axis to X and Y), move the target to the end of the tram bar and rotate the spindle. 2. As with the A-axis, begin at 0 degrees, zero and rotate 180 degrees.

  • Page 51: Measuring Sawmills

    Measuring Sawmills The critical alignments for a sawmill ensure that the log carriage is traveling straight and flat, is perpendicular to the blade, where the mill is cutting specific board lengths, and parallel to the blade, where the mill is cutting/shaping board lumber. The L-733/L-743 Triple Scan Laser systems offer the fastest and most accurate way to align sawmills on the market today.

  • Page 52: Checking Support Rollers For Squareness

    4. Then the L-106X Laser Translation Stage is used to translate (move the laser with very little angular change) the laser plane so both targets read close to zero, usually the tolerance is .010 in. (0.25 mm). This means the laser is now on the centerline of the machine. 5.

  • Page 53: Checking Saw-Blade Squareness

    (rotate the fixture/roll to put the target as close to the laser as you can and then sweep it through the arc to the other side). First, zero the target in the near position. Then rotate the roll so the target/fixture are as far away from the laser as possible (far position).

  • Page 54: Checking Saw-Blade Parallelism

    Checking Saw-Blade Parallelism To check the parallelism of saw blades that cut parallel to the carriage travel, the setup procedure for “straightness” above is followed. Place the A-1519-2.4ZB target on the blade at the closest point to the laser (3:00) and zero. Rotate the blade 180 degrees so the target is at farthest point on the blade from the laser (9:00).

  • Page 55: Roll Alignment Buck-In And Laser Transfer Procedure

    The vertical parallelism or levelness can easily be checked using a machinist level. Hamar Laser provides two systems for roll alignment: The L-742W Ultra-Precision Roll Alignment System for printing presses and paper machines, and the L-732W Precision Roll Alignment System for lower-accuracy roll alignment applications, such as rubber mills and textiles.

  • Page 56: The L-742 Alignment Procedure

The following section provides suggestions choosing a reference and step-...
  • Page 57 Here’s how the process works for picking up a reference roll: (keep in mind that using the L-742W or L- 732W is like having two walls, both perpendicular to each other, 100 ft. (30.5 m) in radius and very flat). 1.
  • Page 58 3. Adjust the height of the target by loosening the thumb screw and sliding the post in/out of the magnetic base until the target detects the laser plane. 4. Zero the value for Target 1 using Read15 in the R-1356-2.4ZB PDA Readout and move the target to the far end of the roll.
  • Page 59 5. “Buck in” or tilt Laser Plane #1 (LP#1) using the Yaw Adjustment until Target #1 reads zero at the Far Point. Move Target #1 back to the Near Point, re-zero, and repeat the process until the target reads zero at both locations, which usually takes 2-3 tries.
  • Page 60 7. Since the LP#2 is perpendicular to LP#1, LP#2 becomes the offset centerline of the mill. This offset centerline has a range of 100 ft. (30.5 m) on either side of the laser. 8. Place Target #2 and #3 on floor fixtures at both ends of the machine and adjust until the laser beam hits the middle of the...
  • Page 61 10. Adjust the yaw adjustment on the laser base so that LP#2 is tilted until both Target #2 and #3 show the same readings. LP#2 is now parallel to the offset centerline. Note: The readings do not have to be zero, but just the same number and same sign.

  • Page 62: Remote Buck-In Formula

    13. Since the laser generates a plane, rolls at any elevation in that section that are within 2 ft. (610 mm) horizontally of the laser plane can be measured for parallelism without changing the setup of the laser. Remote Buck-in Formula Often in Roll Alignment, the laser has to be far from the edge of the machine.

  • Page 63: Using Read15 For Remote Buck-Ins On Rolls

    Using Read15 for Remote Buck-Ins on Rolls The Two-Point Buck-in tab is used to make the process of making the laser parallel (bucked-in) to two reference points easier. There is a short procedure to follow that requires measuring the dimensions between the target and laser.

  • Page 66: Arc Measurement Method - Sweeping Through The Arc

    Arc Measurement Method - Sweeping Through the Arc For hard-to-reach rolls that are farther than 2 ft. (610 mm) from the laser, or where the roll radius is greater than 2 ft., the Arc Measurement Method must be used to get accurate results. In this method, instead of using the bullseye level, the target is swept through an arc to find the Top Dead Center (TDC), or the highest point on the arc that is tangent to the laser plane.

  • Page 67: Tramming Method For Hard-To-Reach Rolls

    Tramming Method for Hard-to-Reach Rolls There are times when the side of the roll is impossible to reach with the target. In this case, we can attach a tram bar to the end of the shaft and put the A-1519-2.4ZB Target on it. Rotate the shaft to 12:00 and zero it in Read15.

The word is a contraction of “NORMal-INverted,” which briefly describes the method. It is quite similar to the four clock readings taken with dial indicators but uses a laser and a target instead.
  • Page 78 The readout always shows the displacement between the Target Center and the Laser Beam Center. When the Target Center is not on the True Bore Center, the numbers and the signs on the readout will change when the target is rotated because the Target Center is moved to a different location in relationship to the laser beam.

  • Page 79: Appendix C - Care And Cleaning Of Target Optics

    Appendix C – Care and Cleaning of Target Optics The proper care and cleaning of optical windows and/or lenses of Hamar Laser’s position-sensing devices (targets) assures optimum performance. Contaminants on an optical surface increase scatter, absorb laser energy, and eventually degrade the accuracy of the position-sensing devices. Because cleaning any precision optics risks damaging the surface, optics should only be cleaned when absolutely necessary.

  • Page 80: Appendix D - Coping With Atmospheric Effects

    Appendix D – Coping with Atmospheric Effects The performance of a laser system is affected by turbulence in the atmosphere. The accuracy of the system is .0001 in/10 ft between the laser and the target in typical machine shop conditions. This accuracy can be lessened by a factor of 2 in the winter when the air is cold and dense and can improve by a factor of 2 in the summer when the air is hot and humid and not very dense.

  • Page 81: Reducing Atmospheric Effects With Fans

    Reducing Atmospheric Effects with Fans The most practical way of eliminating vertical temperature gradient and substantially reducing the fluctuations caused by turbulence is to place a fan behind the target with the air blowing toward the laser. When fans are used in conjunction with the “slow response” position on the readout switch, the effects of turbulence can be reduced up to a factor of 10 and vertical temperature gradient can be virtually eliminated.

    When performing roll alignments, it is often necessary to use floor benchmarks at the side of the machine as a reference. Hamar Laser offers floor plates on which to mount targets so that these floor benchmarks may be used as a reference.
  • Page 94 2. Level the floor plate by adjusting the two thumbscrews. Be particularly careful as any out-of-level condition can influence the target centerline. 3. Record the target reading, paying close attention to the plus (+) or minus (-) signs. 4. Rotate the entire floor plate 180°. Be sure that the target face is rotated to receive the laser beam and is square to the incoming beam.

    Figure 43 – Left to right: L-700, L-705, L-720 and L-723 Targets Any of the following targets may be used with any older laser manufactured by Hamar Laser. Each target, however, was developed with a specific purpose. The list below provides descriptions of the most commonly used targets and their capabilities.

It is ordinarily used with a self-centering adapter that can be placed in various locations inside of a continuous bore. The A-510 target was developed specifically for extruder barrel to extruder gearbox alignment, but it has also proved very useful in a number of other bore applications.

    Readouts The R-307 Digital Readout The Model R-307 is a portable two-axis readout used for measuring a stationary laser beam. Used with the T-251 Scanner Preamp, the R-307 can also measure data from single axis scanning targets (see Figure 46). The R-307 Readout can display data supplied by the A-510, A-517 (T-214 with stand), T-212, T-218 and the T-261 targets.

    Three-Point Buck-In Procedure Using Multiple Targets This method requires three A- 517 Targets and three readouts. The procedure is basically the same as with one target but saves the time required to move a single target to the three different footprints.

    Repeat this until both positions read zero and no further adjustments are necessary. Note: Place the target in exactly the same place each time you move from near to far or from far to near. Marking the footprint is usually the best way to ensure that you are back in the same spot each time you move the target.
  • Page 110 Close Buck-In The close buck-in procedure can be remembered by the rule, “Zero Near, Point Far.” Buck in the laser beam by zeroing it on the near target, and then tilt the entire laser unit to "point" the laser beam, centering on the far target.
  • Page 111 If the calculated Set Point exceeds the linear range of the target, (.1 in. or 2.5mm) the laser unit itself must be moved by the Set Point amount. New measurements must then be taken for both targets and a new set point calculated. Figure 54 shows how to move the laser depending upon the sign of the calculated Set Point.
