Measurement & Inspection

Manual and automated analog and digital gages, instruments, scales, tests and other devices, integrated systems and techniques used to report, record, and manage the data of precise physical dimensions, weight, temperature, pressure, current, voltage or other process value being generated from the forming, fabricating, welding or cutting of material.      

Direct Load Position Sensing with Secondary Feedback Encoders

To help verify machine tool accuracy in closed-loop motion control systems, direct load monitoring using secondary feedback encoders eliminates common sources of position error — mechanical backlash, non-linearity, and hysteresis — and saves money along the way.

Learning New Tricks with Ballbar Analysis

The shop tests X and Y on VMCs, X and Z on the lathes and full Y-Z testing on a few machining centers. 
Advanced ballbar testing enables this semiconductor component supplier to achieve better-than-new machine tool accuracy and extend machine life for unconventional silicon processing.
Coordinate Measuring Machines

LDI Distributes Tomelleri CMMs in North America through Regional Resellers

At the other extreme is the 5-axis Space MICRON arm, with a very small range with ultra high accuracy (4 micron+L/50 mm, 250 mm range) that approaches stationary CMMs. The MICRON is ideal for measuring small parts with precise tolerances. It is an articulated measurement arm with a revolutionary design and axis configuration that allows inspection of parts with great accuracy and accessibility, more quickly than any other stationary or portable CMM.(Click on photo to enlarge it)

Laser Scanners

Replacing Tactile Probing with Laser Scanners

A close-up of one of the XC65Dx-LS laser scanners being used on a continuous wrist CW43 interface. Incorporating three lasers in a cross pattern, the XC65Dx-LS captures full 3D details of features and surfaces in a single scan.
This technical assessment explains how the new inspection methods for diagnostic measurement of sheet metal components and body-in-white assemblies at this Turkish automotive manufacturer involves cross scanners being used on coordinate measuring machines.
Non-Destructive Testing

Emerging Trends in Nondestructive Testing

This review covers equipment such as the MAXIMA™ ML-3500 Series ultraviolet lamps from Spectronics that allow NDT inspectors to see the smallest surface defects, hydrocarbon contamination and other flaws that escape less powerful lamps,
This review of some new products shows how advanced technologies are bringing flexibility and a wider range of applications to NDT inspection booths, pre-inspections and screening applications used in shops.

Laser Encoders Deliver Part-Per-Million Accuracy in Composite Machining

The Composites Machining Center achieves repeatability of 0.0381 mm (0.0015 in) on its long X-axis using HS10 and HS20 laser encoders for position feedback.
Laser encoders from Renishaw deliver part-per-million accuracy during week-long machining cycles on 40 meter long composite wing skins being built by Flow Corporation. 
Software

All-Touch CMM Software

TouchDMIS reduces traditional CMM software to just eight Function Buttons which, when selected, open the appropriate Function Window. All open windows offer ‘thru-view’ sight of displayed graphics. Many windows offer a ‘flip button’ for window flipping to display further advanced functions and capabilities for expert users. The software graphics area bleeds to the edge of the touch screen with all software buttons floating atop the graphics.
This touch technology introduces smart phone productivity into the operation of coordinate measuring machines, portable arms and laser trackers.
Surface Roughness/Finish

Prerequisites for High Surface Quality

The gigantic stainless steel Cloud Gate sculpture by the artist Anish Kapoor that is located in Chicago’s Millennium Park was polished by 24 specialists for several months as the final step. The sculpture weighs over 99 metric tons and has a seamless 10 m x 20 m x 13 m surface that mirrors the Chicago skyline.
The flawless surfaces required in mold making demand large cutting volumes during the roughing sequence, but a perfectly finished surface at the end. This analysis from Heidenhain examines how, along with high quality machine tool mechanics and control performance, the optimal milling result necessary to do this depends heavily on the measuring technology.
Measurement & Inspection: Products

Dorsey Standard Bore and Snap Gages

Dorsey Standard Bore Gages are offered from sizes 1.00 in to 36.00 in and are available with depth extensions to 36 in (other lengths available to 144 in). Depth extensions are available both in steel or light weight, thermally stable carbon fiber. SSG Snap Gages are available from 0-1 in to 24 in sizes. Larger Long Range SSG style snap gages are also available. Solid carbide anvils feature a generous lead radius to protect the part being measured.
These U.S.-made gages are built to the same exact specifications and precision as the original Standard Gage Products.
