Abstract

To improve machining capability of diamond turning of hierarchical structured surfaces, fast-tool-servo (FTS) turning using a sharp point diamond cutting tool (tool tip width <30 µm) is proposed to generate micro grooves on freeform surfaces. An embedded measurement probe is employed to improve the tool alignment accuracy and also to realise on-machine surface measurement (OMSM) of FTS machined surfaces before surface micro-grooving. A self-developed controller board is used to collect and synchronise all signals between the machine tool, FTS controller and measurement system. The feasibility of the proposed method is demonstrated through successfully generating micro grooves on freeform lens array and an Alvarez lens.
