Kinematic Mount Selection for Optical Scanning Assemblies
Kinematic mount selection for optical scanning assemblies isolates substrates from thermal and dynamic distortions while maintaining sub-microradian repeatability.
Wire EDM Flexure Profiling
Meaning
Subtractive manufacturing methods utilize a continuous thin wire to erode conductive materials through electrical discharges, and wire EDM flexure profiling produces high-precision, low-stiffness joints used in precision mechanism design. This wire EDM flexure profiling technique allows for the creation of extremely thin, uniform metal strips that act as frictionless hinges. The process avoids the mechanical stresses and thermal distortions associated with conventional milling.
Tooling Geometry
The diameter of the wire dictates the minimum internal radius of the flexure cutout, which directly influences the stress concentration points. Precise control of the wire path allows for the generation of complex parabolic or filleted profiles that improve fatigue life. This geometrical precision is necessary for applications requiring millions of cycles without failure.
Material Selection
High-strength alloys are chosen for their high yield strength and elasticity. These properties allow the flexure to undergo repeatable deformation without damage. Wrong choices lead to premature failure.
Production Yield
Machine feed rates must be carefully optimized to balance throughput with the risk of wire breakage. When scaling from prototype development to production runs, a supplier’s demonstrated rate often falls below initial forecasts due to the slow speeds required for high-accuracy cuts. Fast feeds can cause wire lag, leading to part rejection.
