Airborne inhalable particulate in the workplace represents a significant health hazard. One of the primary sources of this particulate is mist produced through the application of cutting fluids in machining operations. One of the important mechanisms for the production of cutting fluid mist is the atomization mechanism. In this paper, atomization is studied by applying cutting fluid to a rotating workpiece such as found in turning. An imaging system is presented for the study of the atomization mechanism. The imaging system extends the size measurement range typically achievable with aerosol sampling devices to consider larger particles. Experimental observations from the imaging system reveal that workpiece rotation speed and cutting fluid flow rate have significant effects on the size of the droplets produced by the atomization mechanism. With respect to atomization, the technical literature describes models for fluid interaction with the rotating workpiece and droplet formation via drop and ligament formation modes. Experimental measurements are compared with model predictions. For a range of rotation speeds and fluid application flow rates, the experimental data is seen to compare favorably with the model predictions.

Mist Formation

Abstract In Part 1 of this paper, models were developed to describe the formation mechanisms and dynamic behavior of cutting fluid mist. This part of the paper focuses on experimentally investigating mist formation during the turning process, and then simulating the dynamic behavior of the mist droplets, including the distribution and the mass concentration. Simulation results are compared to experimental measurements to validate the theoretical models presented in Part 1. It is seen that the model predictions adequately characterize the observed experimental behavior.

Machining process should also consider environmental aspect, with power consumption as one of the criteria. Cutting parameters can be optimized to minimize power consumption. This paper takes a study on turning of nickel-based hastelloy under dry condition (no cutting fluid) which varies cutting speed (150, 200, and 250 m/min) and depth of cut (0.5, 1.0, and 1.5 mm). Power consumption of particular machining process at various cutting parameters was derived and calculated. It was found that minimum power consumption was shown when the turning process was performed at the lowest cutting speed and depth of cut.

This paper will discuss how the influence of different cutting fluid on surface hardness, how different spindle speed affect surface hardness, and are there interactions between cutting fluid and spindle speed on surface hardness of workpieces produced by conventional lathe. In this study, the variables that are varied are the cutting fluid and spindle speed. The cutting fluid used is: dromus, used oil SAE 40 and used cooking oil. While the spindle speed used is 370 rpm, 665 rpm, and 1040 rpm. Then the hardness of the workpiece surface is tested from the lathe process by varying the cutting fluid and the spindle speed. From the results of the hardness test on the surface of the workpiece, it can be concluded that: the greatest value of the surface hardness of the workpiece is obtained in the lathe process using dromus cutting fluid and the spindle speed used is 665 rpm. Whereas the smallest workpiece surface hardness value is obtained when using dromus cutting fluid using spindle speed of 1040 rpm. Cutting Fluid and Spindle Speed has a significant effect on surface hardness in the turning process of AISI 4140 steel

1045 Steel

The increasing technological advances obtained both in the development of new materials and of machine tools increased the demand for the machining processes and in addition, the use of increased cutting fluids. However, it’s necessary to have characteristics that don’t harm the environment and the operator. In machining processes, cutting fluids, when properly chosen and applied, may reflect benefits during the manufacturing process. This work evaluated the performance of a commercial cutting fluid by comparing it with vegetable oil extracted from carapa guianensis in the abnt 1045 steel turning process. The cutting speed (vc), tool feed (f) and depth (ap) and the influence of the use of both of them on the metal was verified with the following variables: chip analysis, surface finish, cutting temperature and tool wear. It was observed that with the use of andiroba oil, better chip was generated for the safety of the operator, higher cutting temperatures in the piece, higher tool wear and better surface finish with a difference of 23% compared to commercial cutting fluid. Thus, the fluid from andiroba based on the conventional application demonstrated a viable alternative in the turning process of abnt 1045 steel, because it’s biodegradable and reduces petroleum-based cutting fluids.
