Grinding Aspheric surface
- Tool selection (Ball,Weel, and Cup)
 Ball type Tool |
 Weel type Tool |
 Cup type Tool |
- Blank set-up (Geometry, Initial sag and Central thickness (CT))
- Transferring the aspheric lens equation to CNC machine language (Radius of curvature, Conic constant k, and Aspheric coefficient a1 to a20)
- Tool parameters (Cut direction, Head angle, Lens rpm, Tool rpm, Feed rate)
- Aspheric grinding (Best fit sphere BFS, Asphere cut, Metrology, Final correction cut, and Center thickness CT). Edge (optional)
