Carbon fiber reinforced plastic composites are used in many applications due to their superior properties. Drilling is the most frequently used machining process due to the need for assembly of carbon fiber reinforced plastic parts in mechanical structures. Rotary ultrasonic machining has been successfully used in drilling carbon fiber reinforced plastic composites. Reported investigations on rotary ultrasonic machining of carbon fiber reinforced plastic cover several output variables (including cutting force, torque, surface roughness, material removal rate, fiber delamination, tool wear, and power consumption). However, there are no reported studies on cutting temperature in rotary ultrasonic machining of carbon fiber reinforced plastic. This paper presents an experimental study on cutting temperature in rotary ultrasonic machining of carbon fiber reinforced plastic using two measurement methods (thermocouple and fiber optic sensor). Comparisons between these two methods are made and relations between input variables (ultrasonic power, tool rotation speed, and feedrate) and cutting temperature are experimentally determined.

A new approach is introduced to refine the analysis for the chip energy in the highefficiency deep grinding process, by considering the heat partitioning at the chip formation area. The analysis for the chip-work subsystem has been combined with the whole thermal system to derive the grinding temperature on the workpiece surface. The variation of chip temperature with material removal rate under different grinding conditions was investigated, and the relationship between the chip temperature and workpiece contact temperature was derived. The grinding temperatures obtained using different approaches were compared with 'measured temperatures', estimated from the depth of thermal damage observed on ground samples.

“…However, the decomposition of highspeed steels occurs from 400-450°C during the heating. Walton et al (2006) found that the effect of the heating rate due to the grinding conditions have a significant influence on the A3 austenitic transition temperature. A review of early works concerned on hardening of alloy steel surfaces by grinding was done by Torrance (1978).…”

Investigations of the surface layer characteristics of selected kinds of low-alloy high-speed steel after grinding were carried out. They were carried out on the flat-surface grinder with a 95A24K grinding wheel without cooling. The influence of grinding parameters was defined especially for: the quantity of secondary austenite, surface roughness, microhardness and grinding efficiency with a large range of grinding parameters: grinding depth 0.005–0.035 mm, lengthwise feed 2–6 m/min, without a cross-feed on the whole width of the sample. It was found that improvement of grinding properties of low-alloy high-speed steels is possible by efficient selection of their chemical composition. The value of the grinding efficiency is conditioned by grinding forces, whose value has an impact on the grinding temperature. To ensure high quality of the tool surface layer (i.e. a smaller amount of secondary austenite, lack of wheel burn and micro-cracks) in the case of sharpening of tools made of low-alloy high-speed steel, the grinding temperature should be as low as possible.
