The processing of a magnesium-alumino-silicate matrix, SiC fibre glass-ceramic matrix composite using a pulsed Nd-YAG laser

Rotary ultrasonic machining of ceramic matrix composites: feasibility study and designed experiments

“…Ramulu et al proposed machining of CMC (TiB 2 /SiC) by electrical discharge machining (EDM) [7]. Tuersley et al investigated processing of CMC (magnesium alumina silicate matrix, SiC fiber glass reinforcement) with a pulsed Nd-YAG laser [8,9]. Carroll et al presented machining of dense SiC/SiC woven composites and green Si 3 N 4 /BN fibrous monolithic composites using a CO 2 laser [10].…”

Laser Drilling of Metallic and Nonmetallic Substrates

“…Tuersley et al (220) investigated the cutting and drilling of a composite material consisting of silicon carbide (SiC) fibers in a chemical-vapor-infiltrated SiC matrix with a Nd:YAG laser and reported good quality of laser machining by optimizing the assist gas pressure and location of the laser focus point. holes and blind vias midinfrared CO 2 laser, higher harmonic UV Nd:YAG and excimer lasers have been utilized (22,25,52,68,85,223).…”

Improving hole exit quality in rotary ultrasonic machining of ceramic matrix composites using a compound step-taper drill

“…Improving the efficiency and reducing the cost of machining FRCMCs has thereby drawn considerable research attention. In the past two decades various conventional and novel methods have been introduced to attempt to improve the machining of FRCMCs, including rotary ultrasonic machining (RUM) [5][6][7][8], grinding [4,[9][10][11][12][13], electrical discharge machining [14], laser machining [15], abrasive water jet machining [16], ultrasonic machining [17], ultrasonic vibration-assisted grinding [18], and ultrasonic vibration-assisted filing [19].…”
