Abstract

In the manufacturing nowadays there are many methods that have been introduced due to the improvement of the coolant supply used in manufacturing industry. For example, dry cooling technique, high pressure cooling technique, wet cooling technique, mist cooling technique and minimal quality lubricant technique. The dry machining and wet machining both give a bad impact to the industrial workplace. Thus, the technique of minimum quantity lubricant (MQL) technique is introduced to overcome these problem. Therefore, the idea of this project is come from the MQL method that use minimal quantity of the cutting fluid but the coolant supply is to be controlled by using Programmable Logic Control (PLC) which is able to control the duration time for coolant supply during the machining process. The PLC program should be constructed where the duration of the coolant supply must be insert and controlled by the ladder diagram which have been controlled by using the nozzle. The experiment are conducted for flooded and non flooded coolant using the same interval time. The flooded experiment required in order to measure the quantity of the coolant supply during the machining process while the analysis is performed to obtain the optimum duration of coolant supply during the machining process by referring to the workpiece surface quality and the weary of the machining tool. The non flooded technique is used to obtain the optimum feed rate, spindle speed and the depth of cut. The performance of each interval time of coolant supply is analyzed through in term of surface roughness of the workpiece. Therefore, result of this experiment show that the make use of the automated cooling technique is proven for large improvement compared to the conventional cooling supply such as dry cooling technique and the wet cooling technique. Furthermore, the optimum cutting parameter of the spindle speed, feed rate and the depth of cut are also defined.
