“…It is now established that cutting tool surfaces protected by the diamond-like carbon (DLC) coatings, prolong the tool life by at least an order of magnitude compared to the uncoated HSS drills [1][2][3][4][5]. H-DLC coated HSS and WC-Co exhibited almost similar tool lives as the CVD diamond coated tools [1] and they were more effective than the conventional TiN, TiAlN and CrN coatings [6].…”

“…The use of hydrogenated DLC (H-DLC) coatings containing about 40 at% hydrogen on the tools used to machine aluminum reduced the torque, thrust force and minimized the material transfer during dry drilling and tapping operations [3,4]. It was also shown that nonhydrogenated DLC with less than 2 at% hydrogen (NH-DLC) when used with water as minimum quantity lubricant (30 ml/h) would serve the same purpose [3].…”

“…To improve the surface properties of the mould by coating diamond-like carbon (DLC) on its surface, thereby the reliability of the mould can be improved significantly, which often has a multiplier effect. Mould surface coating technology can improve the performance of the mould surface, which has caused enough attention in related fields, and using reasonable coating technology and process parameters have a crucial impact on the quality of the coating [5,6].

Diamond-like carbon film has the similar excellent properties to diamond film as one of amorphous carbon films, such as high hardness and elastic modulus, high thermal conductivity, low coefficient of thermal expansion, and extremely low friction coefficient. At present, diamond-like carbon film has been widely applied in various fields such as automobile, mould, tools, and so on. In this paper, a new diamond-like carbon coating containing Cr transition layer is deposited based on the cathodic arc technology. The thickness, adhesion, friction coefficient, and other relative performance of the coating are measured and analysed. The results indicate that the bonding status of the new film has been improved obviously, compared to that without a transition layer. The proposed method also provides a new technical guidance for the preparation of diamondlike carbon with stronger adhesion strength.

“…With regard to the tapping of Al-Si alloys, S. Bhowmick et al,. measured the side surface temperature during tapping by using an infrared thermometer, but they did not measure the tool edge temperature [4]. Therefore, the relation between the tapping conditions and the tool edge temperature is still unclear.…”

This paper proposes a method for measuring the tool edge temperature during tapping. The infrared ray from the tool edge of the tapping tool was measured using a two-color pyrometer with an optical fiber. In addition, the vibration caused by contact between the first-act tool edge and the workpiece was sensed by an acceleration pickup. The outputs of the pyrometer from the tool edges and chips could be distinguished by analyzing the cutting behavior in the tapping process. The tool edge temperature was successfully measured for tapping of AISI 1045-based free-machining steel and stainless steels. The cross-sectional cutting area appears to control the tool edge temperature. The maximum tool edge temperatures with thee two steels at a cutting speed of 30 m/min reached almost 300 and 400 ºC, respectively. The cutting torque for stainless steel 303 was 3.4 N•m lower than when tapping stainless steel 304. The tool edge temperature for stainless steel 304 reached the maximum value of 510˚C. The temperature for stainless steel 303 was about 100˚C lower than of stainless steel 304.The tool edge temperature for stainless steel 304increased linearly with the cutting speed. The rate of increase in the tool edge temperature with increase in cutting speed from 25 m/min to 30 min was larger than that from 20m/min to 25min. Therefore, the tool edge surroundings apparently became harder with an increase of cutting speed.
