Lap Calculator settings and results are explained in the following table:
Settings
Description
Number of Guns
Number of guns arrayed horizontally on the reciprocator. It is always assumed
that there is only one array of guns and they are all on the same horizontal
plane. This number is taken from the reciprocator configuration setting and
cannot be changed.
Number of Laps
How many times the effective fan width passes over a certain point. Typically,
the more times the better the powder coverage will be.
2 = normal quality,
4 = fine quality,
6 = extra fine quality.
NOTE:
At any given conveyor speed, the higher the number of laps, the faster
the reciprocator speed required. Make sure that the reciprocator is not going
so fast that the fan pattern collapses. If the fan pattern collapses or the
maximum reciprocator speed is exceeded then select a lower number of laps.
The number of laps is set on the reciprocator configuration screen.
Spray Pattern Width
Width of one spray gun fan pattern. Assumes all spray guns on the
reciprocator have the same pattern width and there is no overlap. If guns are
mounted so that their fan patterns overlap, then enter the average fan pattern
width (total width of pattern created by all guns, divided by number of guns).
The spray pattern width is set on the reciprocator configuration screen.
Conveyor Speed
Can be the actual speed (Auto) or entered manually (Manual) if experimenting
with the effect conveyor speed has on reciprocator speed.
Overtravel
Distance above and below a part that reciprocator moves guns. Can be actual
distance (Auto) taken from default or preset settings for the current part, or
entered manually (Manual) if experimenting with the default or preset
turn-around or overtravel settings.
Part Height
Height of part. Can be the actual height (Auto) of current part, or entered
manually (Manual) if experimenting with settings.
Results
Description
Stroke Length
Calculated total length of stroke. (Overtravel x 2) + Part Height
Reciprocator Speed
Calculated average speed required by settings to cover part. Actual
reciprocator speed cannot be set higher than maximum speed limit.
Cycles per minute
A cycle is defined as complete when the guns return to their start position.
Number of up and down cycles per minute resulting from settings.
