Fowler Thread Trend System Helps Shop Cut
Cost's and Increase Quality Control
August 1996 Advance Turning and Manufacturing Inc., really
lives up to its name these days, particularly since the specialty
machine shop has begun using a new thread gaging system from
the Fred V. Fowler Company.
principal production comprises turned and milled machine parts
for the aerospace and other high precision industries, parts
of tight, demanding tolerances which require sophisticated
manufacturing practices and knowing how to hold microns during
Trend Gaging System of Fred V. Fowler Company, first acquired
by Advance turning last year (1995), "has made the difference
between having a fixed versus a variable reading. which is
much more precise," according to Tom Rooney, Advance Turning's
continues Rooney, "it was necessary to have different thread
rings for each external size. Now, we can always tell exactly
where we are on the new machine, which is adaptable to all
sizes of the same pitch -- from #4 to 2-1/4" diameter pieces
and threads from 6 to 48 pitch"

is one of many companies who rely on Advance Turning for high
quality screw components. They depend on Advance to supply only
the best. Founded in 1972, Advance Turning maintains two atmospherically-controlled
inspection laboratories for its metrology instruments. Its shop
floor is configured into machine "cells," allowing one machinist
to perform different operations on the same job.
that the company uses standard rolls in its production of
these threaded products and does all settings of the new instruments
in a gaging laboratory before they are taken to the turning
machines in production. Formerly, he added, the company had
to purchase thread rings for each external size, while today
it can handle all sizes of the same pitch. "With this instrument
and the application of statistical process control systems
we can track our quality better," he says.
Trend Makes Difference...
| The instrument
is ideal for setting up and monitoring thread production, and
its simple design allows even unskilled personnel to obtain
accurate readings. Rolls are adjusted with a standard micrometer
or caliper --and no templates or special tools are needed for
quick, precise setups. Essentially the instrument controls quality
of fit by detecting roundness irregularities. Although Advance
Turning is in the process of converting its manual SPC system
to an automated one, it can take advantage of an electronic
indicator on the instrument to make the transition.
the system is ideal for special applications such as circlip
grooves, plain outside diameter roundness and more. The screws
for the rolls are recessed, which allows measurements to be
made close to the shoulder of a workpiece. The device can
accurately measure both pre-plated and post plated threads.
"We only need
a set plug to set the size of the parts being checked," Rooney
adds. "Overall, we are now obtaining a 20% cost saving with
the new instrument.
