a single tool that could measure diameters, heights and depths,"
said Ciepiela. "Often, we had to scrounge around the
plant to collect enough measuring devices to check the parts
produced by our cylindrical grinders."
computer numerical control (CNC) machine operator, and Al
Sirois, quality technician for Marland Mold, said adding the
gage has made it much easier to measure certain parts such
as, the position of a hole in a block of steel. With the height
gage, if hole positions are on the length of a bar, diameter
and location is measured in a single operation. "If you
use a regular indicator, height gage and transfer stand, you
would have to sweep the top and bottom of the hole and transfer
to the indicator then to the height gage," said Sirois.
"With the Z-Cal, you cut out 75% of these steps, beside
getting all the calculations done for you."
The gage can be
operated with one hand and measures heights, lengths and slots,
as well as centerline locations and center distances, and
internal and external diameters using a light measuring pressure.
It has an accuracy of 0.00014 inch (0.004) millimeter and
0.00024 inch (0.006) millimeter.
Marland Mold uses
the optional probes that have diameters of 1 millimeter and
2 millimeters for miniature parts. The Z-Cal has a repeatability
of 0.00008 inch @ ±2 sigma.
According to Ciepiela, the gage has reduced the number of
rejected parts caused by human errors and made the measurements
more reliable as well as being easy to operate.
"With the Z-Cal, which is easy to operate, we're saving
30% to 40% of the time it used to take to make measurements,"
