Abstract

In the modern manufacturing industry, dry machining and wet cooling techniques are two (2) types of cooling techniques that are commonly used. Both cooling techniques however, have their drawbacks which result in adverse effects on the workpiece, tooling, health, economy and environment. Moreover, with the used of wet cooling techniques, the cost for disposal of cutting fluids is capable of reaching two to four times higher than their purchase price. This is because cutting fluids are non-biodegradable and requires expensive processing before being disposed. Thus, the idea of using Minimal Quantity Lubrication technique and PLC is inspired to regulate the quantity of coolants and the timing of the supply of coolants. Therefore, the aim of this project is to analyse the performance of the proposed automated coolant supply in term of details interval time and at the same time to determine the best surface roughness vs the interval time. For this project the timing is set to close the valve and the valve must open and continue to supply coolants until closing due to time settling after a certain amount of time. The analysis applied in the experiment consists of performance testing of unloaded coolants as well as time-based coolant, where the result refers to surface quality of the workpiece. The performance of each coolant supply which is 1 second to 60 seconds with time interval of 5 seconds is evaluated by obtaining the roughness of the surface from each turning part. The surface roughness is examined and determined using the Mitutoyo roughness tester in Metrology Lab. The result shows that the proposed automated coolant supply system is a promising technique to be used as the best surface roughness of the workpiece was obtained during the interval time of 15 seconds of coolant supply. This result proves that coolant supply needs not to be supplied continuously, as a good roughness is still achievable
