Custom Computerized Gaging
paragraph to go here.
| Custom gage programming
can present the data collected by the inspection unit in a variety of ways, dials, meters,
or columns. A common operator interface is a depiction of the part with
dimensioning that is consistent with the process sheet for that operation.
Dimensions are then filled in with an actual size or deviation from nominal that is color
coded based on precontrol limits

| Custom gage programming allows
dimensions to appear as the operator applies gage components onto the part. When the
inspection unit is part of a gage bench inspection with multiple gages, the data for the
each gage being used can be displayed independently.
Collected data can be
saved and uploaded to an in-house SPC program or charted live for factory floor use.
Custom gage programming can aid in SPC data collection by filling check sheets to ensure
all inspections are being performed. When the manufacturing process consists of
multiple fixtures or spindles, the inspection unit can display optimum offsets and
adjustments for centering the process.
| Another benefit of custom
programming is communicating with paint markers, pin stamps, or lasers to place an
indication on the part that an inspection was performed. When the inspection unit is
part of an automated cell, custom gage programming can send signals for sorting and
rejecting parts as they are inspected.
| The standard inspection unit is compatible with a wide variety
of industry LVDT transducers (eg. Marposs, Solatron, Schaevitz, and Etamic). Air
columns can be connected to a standard inspection unit using either the analog output or
the digital output of the column. The standard inspection unit is not limited to
using only LVDTs, any sensor that produces an analog output may be connected to the
inspection unit provided the signal is scalable, such as laser ribbons, pressure gages,
and strain gages. Digital probes can be used with the inspection unit and programmed
similiar to analog probes when the protocol for the digital probe is provided.
| The standard
LVDT connector is a threaded 5-pin female circular DIN connector (eg. E4N style).
The interchangeable connector plates permit installing the unit in existing setups without
replacing the current probes. The connector plates allow changing connector styles
or adding more probe connections to an existing system. The plates allow 16
connections each, and one plate can be mounted to each side of a standard inspection unit.
An optional modification of the enclosure is required when the gaging system uses
more than 32 LVDT transducers.
auxiliary power supply (24V) for the LVDT signal conditioner is sized to provide power for
discrete I/O components such as proximity switches, limit switches, solenoids, and signal
lights. Hardwire communication to robot controls and PLCs is available when the
inspection unit is a component in an automated cell. A common I/O option is a four
color ( red, yellow, green, and blue ) tower light. The tower light provides a
quick visual status of the current inspection or it can signal the status of the current
operation of an automated manufacturing cell.
The standard inspection unit is 20 inches wide, 16 inches tall,
9 inches deep, and weighs approximately 55 pounds. Two fixed handles are attached to
the top of the unit to facilitate easy portability. Four rubber pad feet are
attached to the bottom of the unit for free standing bench top usage. An inspection
unit can be wall mounted by attaching four optional brackets. The optional brackets
also allow mounting an inspection unit on the outside of a wire-mesh cage when the
inspection gage fixture is robot loaded or part of a pick-and-place system.
| An exhaust
fan and a replaceable external filter are mounted on the sides of the inspection unit
allowing easy preventative maintenance. The gage program includes a routine to
assist in cleaning the touch screen monitor. A 12 foot power cord eliminates usage
of an extension cord in most environments.
