Demanding Growth Industries

PMDi serves fast moving growth industries including aerospace, automotive, computer numerical control (CNC), data storage, medical, military, semiconductor, optics and photonics. Within each industry, PMDi strives to offer unique features that enable customers to create clear competitive advantages.

Optics & Photonics

Fastest, most advanced feedback regulators enable Galvano motors to reach their full potential for laser and extreme UV light source applications. Precise integration of servos, Galvos and lasers is achieved using high-speed digital logic programming.


Full double precision path planning provides higher resolution and accuracy. Mercury Gbit/s real-time communication protocol substantially increases hardware-in-the-loop performance.


Mercury real-time communication enables extremely high rates of data collection and storage, for advancing dynamometer performance.


Customisable path planner and advanced control structuring allow for the implementation of custom kinematics for medical robotics.

CNC Cutting

The highest GCode block rates in the industry are achieved with superior hardware and real-time networking. Motion control technologies specific to routing, waterjets and laser cutting.

Diamond Turning Lathes

Superior form, finish and throughput is achieved using limited jerk and PVT profiles computed in double precision math. Advanced control for air bearings, hydrostatic bearings and spindles.


Advanced control algorithms provide quick settling time and on-the-fly retargeting, allowing for significantly higher throughput for chip processing. Advanced control of air bearing nanometer positioning stages for wafer inspection.
