What is it about?
A surface analytical model computes the accuracy of the surface to be machined and assists in generating precise tool paths for fast tool/slow slide servo (FTS/SSS) diamond turning processes. Three cutting strategies (constant-angle, constant-arc, and hybrid of both) have been successfully evaluated by the proposed model and able to meet the targeted accuracy requirements.

Why is it important?
Fast tool/slow slide servo (FTS/SSS) technology plays an important role in machining freeform surfaces for the modern optics industry. The surface accuracy is a sticking factor that demands the need for a long-standing solution to fabricate ultraprecise freeform surfaces accurately and efficiently.
Perspectives
The analysis of cutting linearization errors in the cutting direction of surface generation has received little attention. Hence, a novel surface analytical model is developed to evaluate the cutting linearization error of all cutting strategies for surface generation.
