“…The DLC coating has a coefficient of friction of 0.1 and is present between the tool and the chip from the initial state, which makes it exactly the right material for the job. However, DLC-coated tools have difficulties in machining carbon-containing workpieces and the use of cutting fluids [17] and their coating life is short in high temperature conditions [18]. Therefore, it is currently desired to extend the coating life.…”

In wet cutting, lubricants are used to improve lubrication, forced cooling and chip evacuation. In particular, improving the lubrication between the tool and the chip results in a lower coefficient of friction, suppressing the tool temperature change and improving the cutting properties. For this reason, tools coated with DLC (Diamond Like Carbon) or diamond have been developed to further reduce the coefficient of friction. However, the tool life is still not sufficiently long. Therefore, in this study, a cutting fluid for polishing tools during cutting was developed and evaluated. First, using the author's previous research, the function, effect and influence of several cutting fluids on milling were identified. Secondly, a new criterion for determining tool life was defined and, based on this criterion, a cutting fluid was proposed to polish the tool during the cutting process. Next, the machining conditions under which the proposed cutting fluid would be effective were identified. Finally, the cutting properties of the proposed cutting fluid were evaluated. The results showed that (1) the cutting fluid was developed to polish the tool during the cutting process and the optimum machining conditions were clarified, (2) the proposed cutting fluid was very effective in increasing the tool life.

“…Before each UVAG experiment, the EDT is set to the machine and undergoes the tool dressing or trueing process as a mirror finish is easier to be obtained with the EDT that has undergone this process [1]. The trueing process is performed using a rotated diamond truer wheel that has also been set on the same machine table.…”

The applicationof electroplated diamond in ultrasonic vibration-assisted grinding can be a candidate to replace the manual mirror finishing of the stainless-steel surface and the ability to characterize the tool and work surfaces is important for understanding the tool-work interaction during the grinding process. In this study, an ultrasonic vibration-assisted grinding on stainless steel surface using the electroplated diamond tool is performed for the tool-work surface interaction diagnostic. The experiment used constant machining parameters, leaving the electroplated diamond tool as the only input variable. The experiment produces nine tool-work pairs for the analysis. A combination of the reversal method and areal surface metrology is introduced to capture and prepare the topography data for characterization. The analysis results show that the combination of the reversal method and areal surface metrology can be used for the electroplated diamond tool working surface characterization in explaining its effect on the ultrasonic vibration-assisted grinding of stainless-steel surface for a mirror finish.

“…For example, elliptical vibration assisted cutting has been used to diamond turn optical quality surfaces in high-wear materials such as steel and glass while extending tool life by a factor of twenty or more [2]. Vibration assisted precision grinding minimizes ceramic subsurface damage and reduces loading on the grinding wheel [2] [3] [4].…”

Hard ceramic optical materials such as sapphire, ALON, Spinel, or PCA can present a significant challenge in manufacturing precision optical components due to their tough mechanical properties. These are also the same mechanical properties that make them desirable materials when used in harsh environments. Premature tool wear or tool loading during the grinding process is a common result of these tough mechanical properties. Another challenge is the requirement to create geometries that conform to the platforms they reside in, but still achieve optical window tolerances for wavefront. These shapes can be complex and require new technologies to control sub aperture finishing techniques in a deterministic fashion. In this paper we will present three technologies developed at OptiPro Systems to address the challenges associated with these materials and complex geometries. The technologies presented will show how Ultrasonic grinding can reduce grinding load by up to 50%, UltraForm Finishing (UFF) and UltraSmooth Finishing (USF) technologies can accurately figure and finish these shapes, and how all of them can be controlled deterministically, with utilizing metrology feedback, by a new Computer Aided Manufacturing (CAM) software package developed by OptiPro called ProSurf. .
