Technical PMMA

CNC machining of PMMA

CNC machining of PMMA: CAD/CAM toolpaths, tools, heat, roughness, vibration, drilling, polishing and inspection of the transparent part. CNC machining of PMMA must be treated as an engineering design subject: it is not enough to select a standard semi-finished material; material, geometry, thickness, transparency, stability and final function have to be controlled together.

Technical role

CNC machining of PMMA must be treated as an engineering design subject: it is not enough to select a standard semi-finished material; material, geometry, thickness, transparency, stability and final function have to be controlled together.

Critical variables

For cnc machining of pmma, the decisive variables include polymerization history, internal stress, filler dispersion, heat sensitivity, optical absorption, surface finish and repeatability. Any one of them can change the quality and reliability of the finished component.

Process route, machining and finishing

The manufacturing route has to connect polymer development, block or casting production, CAD/CAM toolpaths, CNC manufacturing, turning, polishing, bonding or lamination when needed, and final microscopic inspection.

Relevant applications

non-standard transparent components
PMMA blocks, castings and special geometries
technical prototypes and small batches
CNC parts with manual finishing
microscopic inspection and part traceability

Where LMS contributes

LMS can handle cnc machining of pmma as a complete technical project: material research, in-house production, precision machining, manual finishing and traceability part by part and batch by batch.
