Abstract
A non-rigid cutting mechanism has been developed for the machining of materials in micro/nano scale. This mechanism is proposed for the fabrication of micro-structured features, such as micro grooves, on brittle materials, specially, when such features should be fabricated on curved or inclined surfaces, due to the capability of the mechanism developed to fabricate grooves with a constant cutting depth. On the other hand, it is know that brittle materials can be machined in ductile mode (crack free) under a sufficient small depth of cut. To find the critical cutting depth on glass, some cutting experiments were performed on an inclined surface, presenting the results on this paper. At the same time, it was observed the influence of the rake face angle of the tool during the cutting process. As result of this experiment, micro-grooves with cutting depths over 3 microns were achieved on ductile mode.
