Alignment Math Formulas Flashcards
What is cross dial horizontal formula
Cross dial A=
A dial tir reading rotated 180
Cross dial B =
B dial tir reading rotated 180
Cross dial x=
X= distance between dials
Cross dial L1=
L1= distance from A dial to first leg
Cross dial L2=
L2= distance from A dial to second leg
Vertical cross dial formula
Bar sag add too what dial
Subtract too what dial
Add to dial A
Subtract too dial B
If calulaiton for s1 is 5.5 you move towards or away from datum.
Towards
Reverse dialing dial B is where
On top
Reverse dial formula difference is
A plus B not minus
Reverse dial bar sag A YOU add or Subtract
B you add or Subtract
Add on both A and B dials both start at top.
Collinear means?
A single straight line will define the center of both shafts
3 basic types of laser equipment are
- A single reflected beam with a single detector
- A dual beam with dual detectors.
- A single beam with dual detectors.
Single reflected beam/ single detector requirs ?
Allows dynamic interruption ture or false.
A single cord single cord
True
Dual beams Dual detectors requires ?
Allows dynamic interruption
True or false
Two cords
False
Single beam dual detectors requires
Allows dynamic interruption
True or false
Single cord
True
Laser components x5
1.Transmitter/detector
2.reflector
3.bracket
4.stationary machine
5. Machine to be moved
To maintain accurate and consistent reposition of shafts you use a
Inclinometer to set the laser and shafts at the exact rotational locations.
Laser ubit is on what machine
Fixed
The prism reflector is on what machine shaft
Mtbm
Most laser systems requires the laser and shaft to
Rotate together.
Laser range old=
New =
2m (5.56ft)
10m (33ft)
Keep laser above what temp
0 c
