Birmingham, Alabama-based Motion Industries Inc., a leading distributor of maintenance, repair and operation replacement parts, has promoted Greg Cook to executive vice president and chief financial officer, effective April 1, 2020.

Of unique importance today is the role of post-process metrology to validate the integrity of AM builds. One specific reason for this importance is that many parts produced by AM end up in safety critical applications where end-use functionality is of vital importance. The nature and relative roughness of AM surfaces, whether analyzing individual layers within a build, or the surface of a finished part render conventional metrology solutions somewhat impotent. In this article, I review developments from Zygo including work alongside Richard Leach that allow for hitherto unattainable metrology results, which are being used to enhance the use of AM as a production technology by making validation protocols more efficient.

Burr Oak Tool Inc. is a leading producer of dies used to produce two types of fins for window air conditioners. Evaporator fins on the side of the air conditioner inside the window transfer heat from the inside air to the cold refrigerant flowing through the evaporator coil. Compressor fins located on the side of the air conditioner outside the window move heat from the now hot refrigerant to the outside air. Burr Oak Tool dies progressively stretch and reform the fins through a series of metal forming operations that extrude and reduce the thickness of the fins.

Cresco, Pennsylvania-based Weiler Abrasives, a leading provider of abrasives, power brushes and maintenance products for surface conditioning, announced the promotion of John Hobbs to director, national accounts.

The industrial control robotics systems perform, control and monitor a wide range of industrial operations and automated processes. The objective is to improve the overall quality, reliability and precision of these processes.

Seco Tools has introduced a modular toolholder system for manufacturers seeking to improve their productivity with Swiss-style machining. The system enables fast, easy and repeatable insert indexing and tool changes outside of tight machine work spaces. The QC (quick-change) Toolholders also feature Seco Jetstream Tooling and Jetstream Tooling Duo technology for optimal chip control, high-quality surface finishes and extended tool life.

The HH-30D Hybrid Hexapod was developed by ALIO Industries to address the inherent performance limitations of conventional hexapods. ALIO's patented 6-degree-of-freedom (6-DOF) design seamlessly blends and takes advantage of the strengths of serial and parallel kinematic structures while avoiding their weaknesses.
