Astro Machine Works (AMW, Ephrata, PA) specializes in building custom machinery and equipment, as well as machining precision parts to exact customer specifications. They also perform machine repair, welding and metal fabrication, and reverse engineering.

The company serves top regional and national companies such as GE, Hershey, DuPont, Bayer and the U.S. government, and industries such as aerospace, general manufacturing, medical, pharmaceutical, food processing and energy.

Each of Astro Machine’s different applications presents unique challenges, but their work in reverse engineering obsolete OEM parts was a particular challenge. These parts range in size from 1-inch cubes through 48-inch cubes and larger. Previously, AMW used older methods such as hand gages, calipers, micrometers and protractors. These options proved to be ineffective since many of these OEM parts are very complicated, with an array of blended radii and compound angles. Manual tools, even when used carefully, resulted in hit-or-miss accuracy.

Solution

AMW searched for a better solution for their metrology needs. They considered a conventional fixed coordinate measuring machine (CMM), but found a more versatile solution matched their needs: the 8-foot FaroArm Platinum. This tool serves both in-process and final inspection functions, as well as reverse engineering. It can be taken directly onto the assembly floor and secured to custom machine assemblies while manufacturing is still in-process. This provides an integral inspection device that can aid in alignment and part position during various stages of assembly.

Any inconsistencies associated with manual reverse engineering have been eliminated and AMW’s work is now completely accurate, while increasing productivity. What previously took hours of work has been reduced to approximately one-tenth the time. Many of the parts they reverse engineered manually in the past are now being done again so as to bring the accuracy up to their new Faro standards.

Return on Investment

The greatest value to Astro Machine with the FaroArm has been the massive time reduction in reverse engineering obsolete OEM parts. In many cases, the time has been reduced ten fold. “Prior to our Faro solution, it was not uncommon for our more sophisticated parts to take 8 to 50 hours to reverse engineer,” says Designer Dan Hughes. “This time has now been reduced to 30 minutes to 5 hours.” A reduction in time is a reduction in cost, which makes AMW more valuable to their customers.

Astro Machine invests heavily in its technology, and advancements are the cornerstone of their continuous improvement strategies. Not surprisingly then, the FaroArm was well accepted. The implementation process was easy and the learning curve was not steep with the user friendly software. AMW uses their FaroArm on a regular basis for inspection purposes and at the outset of projects for reverse engineering. With the gained versatility of the FaroArm, no part is outside their capabilities.
