Hexagon Metrology rolled out two new products at the recent Westec conference in Los Angeles—one a portable measuring arm, the other moving bridge coordinate measuring machine (CMM).

The Omega portable measuring arm, from Hexagon’s Romer Inc. unit, is described by the company as its most economical tool for multipurpose noncontact measurement to date. It is packaged for 3-D scanning applications such as reverse engineering, rapid prototyping, and noncontact inspection. A complete package includes the Omega articulating arm, the R-Scan line laser scanning probe, and PC-DMIS Reshaper software. Entry-level yet full-featured, the product sells for $56,000 (model 2025/9 ft size) and is offered in three additional sizes: model 2018 at 6 ft; model 2030 at 10 ft; and model 2036 at 12 ft.

The Omega series presents a new series of 3-D portable arms that are fast, intuitive, and promote measurement without constraints, according to the company. Optimized for reverse engineering, the R-Scan noncontact laser scanner offers patented infinite rotation for scanning hard-to-reach areas. The Omega system also features large-capacity inspection, repeatability, automatic color recognition, and real-time display of point clouds and point data.

Included in the package is PC-DMIS Reshaper software, a comprehensive 3-D point-cloud processing program for users who need to handle rapidly generated point clouds and obtain high-quality 3-D meshes. The software collects measurement data "live" from the arm, and rapidly creates and edits 3-D polygon mesh models, which can be exported in a variety of formats for further processing in a CAD program or for printing to a rapid-prototyping printer.

From Hexagon’s Sheffield Measurement brand comes the Pioneer Plus CMM, a moving bridge CMM with scalable options including noncontact scanning capabilities and multiple sensor support—all powered by PC-DMIS software. Hexagon says it is a good solution for the CMM buyer looking for greater flexibility and accuracy in aerospace and other industries.

The Pioneer Plus fully supports a range of sensors including the ScanShark 4Vix line laser scanning probe, the CMM-V vision sensor, and the LSP-X1 analog scanning probe, as well as multiple types of touch-trigger sensors. Several types of sensors can be combined in a single system for true multisensor capability.

The ScanShark 4Vix laser scanning probe enables rapid data collection at 23,000 points per second and is used to quickly and repeatably acquire precision data from geometrically complex areas. The ultra-lightweight scanner includes software filters for various ambient lighting situations and surface finishes—from chrome to glossy black. No spray-on coating is needed.

With indexable vision measurement, the CMM-V vision sensor allows noncontact measurement of parts large and small. The probe's software-controlled, integrated LED illumination enables image optimization for each measurement. The CMM-V can measure hole diameters, precise edge contours, and small features that a touch-trigger stylus cannot easily define. The CMM-V is a useful probe for measuring soft or easily deformed parts, or for inspecting printed circuit boards and other deposited or printed patterns. Since the CMM-V operates inside PC-DMIS as an additional supported probe, contact and vision features can be programmed and inspected in a single program.

The Pioneer Plus also supports the high-accuracy LSP-X1 analog scanning probe head, which supports all the standard probing modes from single-point probing and self-centering to continuous high-speed scanning for fast and accurate form and profile measurements.
