Chris AShworth

Lead Software Engineer

Before joining FlexArm, Chris had more than 27 years of experience in project integration and full retrofitting services (hardware & software).

He has been involved in more than 1000 Delta Tau PMA control projects with varying complexity (2 -72 axes). The following are some of the types of machine tools that he has developed over there years: 2-13 axes water jets, 2-6 axes lasers, 3-5 axes mills, four axes punch presses, 3-5axis milling, Dual coordinate systems lathes, surface & profile type 2-4 axes grinders, 2-40 axes application-specific machines, 2-6 Axis Super or Ultra Precision (Diamond Turning) machines, 2-14 axis.

Friction Stir Welding (FSW) machines, 5-6 axis 3D metal printers, six-axis EDM drilling machines, six-axis riveting machines, etc. He also integrated many 3rd party hardware/software products with the Delta Tau (Omron) control system. Examples would be up to 16 camera vision systems controlling motion based on frame grabber image processing, Galvo lasers, wireless control, ultra-precision displacement sensors, optical seam tracking devices, etc.


Curt Rieman

Engineering Manager

Early in his career, he developed Standards of Procedures (SOPs) for the assembly of electrical components for military and commercial flight systems and engine controls. After that, he managed vibratory conveyor projects through the full life cycle from quote to product design through manufacturing and testing to technical support after installation. After the final assembly, he tested and tuned conveyors to ensure the product met customer requirements and maintained the company ISO 9001 quality system through Internal Audits.

At FlexArm, he focuses on developing processes to provide custom-designed solutions that complement its standard product offering. He was fundamental for assembling and managing a team of Engineers to support customized solution offerings. Curt also supports the Sales team through training and technical support. He is one of the most significant contributors to supporting documentation for the product offering that helps sales and manufacturing operate efficiently.
