Measurement & Tolerance Verification
The measure device for analysis was a Heidenhain Quadra-Chek optical comparator
. A gage R&R showed percent equipment variability of 0.13%, percent appraiser variability of 0.18%, percent repeatability and reproducibility of 0.22%, percent part variability of 100%, and a R-dbar of 0.0005 in.
Rahco Rubber has invested over $1 million in four new high-tonnage vacuum presses for low waste flashless molding, two 500 ton Rep injection presses, a state-of-the-art optical comparator
, an ERP system, mold maintenance equipment and website reconstruction.
To measure the parts under the previous manufacturing methods, a variety of tools were used, from handheld micrometers to 50 power overlays on an optical comparator
. By incorporating the Glebar P4K measurement system, a product can be placed on a fixture, and with a single key stroke, the entire part can be measured and all features checked resulting in a quick pass/fail.
All parts at the end of production process were measured by optical comparator
KEYENCE IM series.
The company stated that the new standards comprise of a Pratt & Whitney Universal Supermicrometer and Labmaster System, as well as a Micro-Vu Spectra Optical Comparator
. This metrology equipment complements existing standards to boost InnoCal's dimensional calibration capabilities substantially.
The Keyence TM-3000 2D Optical Micrometer is designed to combine the functionality of a laser scan micrometer, machine vision system and optical comparator
into a single device.
The mechanical method was performed using a precision optical comparator
to determine the exact angle of the radially-oriented openings of the sectors.
"We used to measure these out in the shop with slip gages and in the lab with an optical comparator
. Pass/fail was good enough.
In addition to the Unimat 2000, Northland Forest Products also utilizes a Weinig Unimat 23-E six-head moulder, a CNC Technologies template maker, Weinig optical comparator
, Rondamat 934 knife grinder and a Baker Model AB 12-inch resaw.
These patents included an automatic die, a hydraulic feed, grinding taps, a safety razor, and an optical comparator
for inspecting threads.
If you need to measure large components, it helps to have an instrument with a large field of view, such as an optical comparator
