摘要：The depth of cut is one of the important parameters of machining. It influences a great number of factors of machining like the surface finish, the tool wear, the temperature/heat, energy/power consumption etc. It is of course obvious that the depth of cut affects the rate of heat generated and consequently the temperature in various degrees depending on the conditions of machining, the material etc. So, in order to reduce the negative effect of high temperature which is as a result of the large heat generated due to high rate of friction at the workpiece – tool interface, cutting fluids and lubricants are used. This research focused on the effect of the depth of cut on the two-way application of cutting fluids. The angle of feeding was varied from 30º to 180º. The feed rate was 0.75 mm/rev and the speed was 125 rpm. It was established that the two-way application of the cutting fluids was most effective in terms of the surface finish when the depth of cut was 2 mm and at angle of 150º. In other words, the lowest surface roughness (8.41 µm) was obtained at this angle and depth of cut. In fact the lowest surface roughness (highest surface quality) and temperature were achieved under all the feeding angles except angle 30º and when the depth of was 2 mm. However, the tool wear values were lowest when the depth of cut was 1.0 mm as compared to other values of depth of cut used. Therefore, the recommended values for the depth of cut are 1 mm and 2 mm in terms of the surface quality and tool wear obtained respectively.
