Conventional Drilling

Float glass, which is a hard and brittle material, is generally machined and drilled using rotary ultrasonic machining and conventional drilling to create products such as solar panels, metrological instruments, etc. But researchers are facing serious issues with regard to tool wear and opting for best shape of tool for the drilling purpose. In this study, blind holes are made on float glass specimen using rotary ultrasonic drilling and CNC conventional drilling process with the aid of multi-shaped tools. The opted tools are namely hollow abrasive tool, pin-pointed conical tool, flat cylindrical tools, and concave circular tool. The entire experimental work is accomplished by considering industrial conditions. Multi-shaped tool’s weight is computed at three stages i.e. (a) fresh tool, (b) after rotary ultrasonic drilling, and (c) after conventional drilling to analyze the overall tool wear. Apparently, micro-studies are used to investigate the phenomena of lateral and end face tool wear while creating blind holes at these three stages. It is revealed that the concave circular tool achieved a minimum percentage of weight loss i.e. 4.92% after conventional drilling and 1.96% after rotary ultrasonic drilling process, which could be preferred for drilling purpose followed by the hollow abrasive tool.

Fiber Matrix Interface

Fiber or whisker reinforced ceramics show improved toughness and strength. Bridging by intact fibers in the crack wake and fiber pull-out after failure contribute to the additional toughness. These processes are strongly influenced by the sliding and debonding resistance of the interfacial region. The present study examines the interface in a laminated 0/90 composite consisting of SiC (Nicalon) fibers in a lithium-aluminum-silicate (LAS) glass-ceramic matrix. The material shows systematic changes in sliding resistance upon heat treatment.As-processed samples were annealed in air at 800 °C for 2, 4, 8, 16 and 100 h, and for comparison, in helium at 800 °C for 4 h. TEM specimen preparation of as processed and annealed material was performed with special care by cutting along directions having the fibers normal and parallel to the section plane, ultrasonic drilling, dimpling to 100 pm and final ionthinning. The specimen were lightly coated with Carbon and examined in an analytical TEM operated at 200 kV.
