Chapter 8 Parallelism Measurements
Aligning the Laser Beam to the Machine's Travel Path
Aligning the Laser Beam to the Machine's
Travel Path
If you are making a coplanar parallelism measurement, you must align
the laser beam to the travel path of one axis only. It is best to align the
laser beam to the longer of the two axes.
If you are making a spindle parallelism measurement, you must align the
laser beam to the axis of the tool's travel path only.
To align the laser beam to the machine's travel path, follow the
instructions in "Aligning the Laser Beam to the Machine's Travel Path" in
Chapter 5. (Although Chapter 5 refers to straightness software screens
instead of PARALLELISM screens, the instructions still apply).
You are now ready to check the alignment for beam strength.
Checking the Alignment for Beam Strength
If you are making a coplanar parallelism measurement, you must check
for beam strength along both measurement axes. You can check either
axis first.
If you are making a spindle parallelism measurement, you must check for
beam strength along the axis of the tool's travel path only.
To align the laser beam to the machine's travel path, follow the
instructions in "Aligning the Laser Beam to the Machine's Travel Path" in
Chapter 5. (Although Chapter 5 refers to straightness software screens
instead of PARALLELISM screens, the instructions still apply).
You are now ready to make parallelism measurements. To make coplanar
parallelism measurements, go directly to "Making Coplanar Parallelism
Measurements." To make spindle parallelism measurements, continue
with "Making Spindle Parallelism Measurements."
