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.

Ballbar Systems

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

Under the Radar

For inline inspection, Laser Radar devices are mounted to 6-axis robot arms that are located on each side of the production line. They automatically reposition the devices to inspect areas that are hidden from the line of sight of a single device location. 
With a need to focus on monitoring process quality during the manufacturing process, this laser radar system provides a unique alternative to the shortcomings of the traditional inspection methods.
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. 

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 Showcase

A wide array of snap gages, ID and OD gages, fixed and adjustable bore gages, depth and comparator stands, and other mechanical comparative gages from Mahr Federal can become faster and more productive than ever before by being configured for wireless data transmission with the addition of a MarCator 1086 or 1087 wireless digital indicator.
A review of some of the latest gages, instruments and systems used to measure and inspect parts quicker and more accurately.

What’s New in Coordinate Measuring Machines

The Shapetracer 3D line scanner from Wenzel changes a coordinate machine into the ideal tool to record and handle point-clouds. Perfect for tool and die making, design model contruction and shops that need to record and work on surfaces and outlines of physical objects.
Here are some of the latest technologies that are bringing new capabilities to CMM applications.

The Future of Dimensional Inspection

The “absolute accuracy” of the MCT225 system guarantees measurement accuracy without time consuming comparative scans or reference measurements; samples are simply placed on a rotary table inside the enclosure and measured without the need for granite or touch probes inside the machine. 
Emerging production techniques like additive manufacturing produce small and highly complex components that cannot be inspected using touch probes or optical sensors. The fusion of metrology and X-ray computed tomography makes it possible to measure and analyze these components for porosity, among other issues, in a single non-destructive operation.
