“…The surface of grinding wheel was smooth with reduced surface roughness ( S a = 1.4 µm and S q = 1.9 µm). To ensure good grinding performance, the protrusion height of grit after dressing should be within 1/3 ~ 1/2 of the grit size [18]. Therefore, another 5-min laser tangential dressing with low fluence was conducted and the bronze bonding materials were melted and then blowed away by the compressed air.…”

“…Deng et al [16] investigated the influence of the spot overlap, line overlap, power, and scan cycles on bond smoothness of the grinding wheel and found that the laser scan cycle should be carefully controlled to obtain well-controlled grain protrusion height. Furthermore, Ackerl et al [17,18] developed a multi-axis synchronized motion platform to improve the profile accuracy of shaped wheels. Various cross-sectional shapes of grooves fabricated by laser have been reported in [19,20].…”

Freeform surfaces including both the aspherical and prismatic concave/convex have been widely utilized in optical, electronical, and biomedical areas. Most recently, it is reported that grinding with structured wheels provides new possibility to generate patterns on hard and brittle materials. This paper reports the latest research progress on micro-grooving glass ceramic using laser structured diamond grinding wheels. A nanosecond pulse laser is firstly integrated into an ultra-precision machine tool and used for the in-line conditioning of super abrasive grinding wheels, i.e., truing, dressing, and profiling/texturing. Meanwhile, an offset compensation method, considering the shifting depth of focus (DoF) at different laser irradiation positions, is proposed to accurately generate various profiles on the periphery of the grinding wheels. Three types of patterns (riblets, grooves, and pillars) are successfully fabricated on the ceramic substrate using the laser textured grinding wheels. The results indicate that the integrated laser system offers high flexibility and accuracy in shaping super abrasive grinding wheels, and the grinding using textured grinding wheels provides a promising solution to generate functional microstructures on hard and brittle materials.

The freeform surfaces including both the aspherical and prismatic concave/convex have been widely utilized in optical, electronical, and biomedical areas. Most recently, it is reported that grinding with structured wheels provides new possibility to generate patterns on hard and brittle materials. This paper reports the latest research progress on micro-grooving glass ceramic using laser structured bronze bond diamond grinding wheels. A nanosecond pulse laser is firstly integrated into an ultra-precision machine tool and used for the in-line conditioning of super abrasive grinding wheels, i.e. truing, dressing, and profiling/texturing. Meanwhile, an offset compensation method, considering the shifting depth of focus (DoF) at different laser irradiation position, is proposed to accurately generate various profiles on the periphery of the grinding wheels.
