“…While depth of cut had a noteworthy influence on cutting force, its effect on surface roughness was quite insignificant. Kumar et al (2012) investigated the effect of spindle speed and feed rate on surface roughness while turning carbon alloy steel specimens on a CNC lathe. The five different alloy carbon steels used for turning were SAE 8620, EN8, EN19, EN24 and EN47.…”

Dry friction depends on the surface topography which, in turn, is governed by machining parameters in addition to several other factors,. Therefore, in order to establish a qualitative relationship among these factors, the surface roughness and coefficient of static friction are measured for specimens machined on lathe and shaper machines with different values of machining parameters. For the case of lathe, the measured Ra value is found to increase with increase in feed rate and depth of cut, whereas, a marginal decrease is observed with increasing spindle speed. Similar results with respect to cutting speed have been obtained for the case of shaper machine. On the other hand, the coefficient of static friction, measured on steel substrate using inclined plane method, is found to decrease with increasing Ra values for both the specimen types.

“…Achieving the required surface roughness is critical for the functional behaviour of a part due to its impact on mechanical properties of the manufactured parts such as fatigue life, wearing, and light reflection, ability to distribute and hold a lubricant between contacting bodies, load bearing capacity and coatings [2,3]. Moreover, surface roughness plays a significant role on machining cost where it is related to the dimensions precision so contributes in reducing assembly time and avoiding the need for secondary operation, therefore cost will be reduced [3,4]. The value of surface roughness depends on numerous factors such as machining parameters, material of cutting tool and its geometry parameters, work piece material and its mechanical properties, generated temperature, machine vibrations and cutting conditions (wet or dry cutting).…”

The current study aims to find the optimum cutting parameters in turning process without using cutting fluids (dry cutting condition) towards sustainable manufacturing. Where the power consumption and environmental pollution increase due to increase of the machining operations in manufacturing field, so to save energy and environment and reduce cost it is important to adopt sustainability in machining processes.The experimental work in this study involves the preparation to a number of experiments on AISI 1045 carbon steel to collect the necessary data for implementing optimization process. The experiments were conducted by changing levels of cutting parameters (spindle speed, feed rate and cutting depth) in CNC turning machine. Surface roughness of the workpiece has been depended as a quality indicator. In addition, the temperature of cutting tool has been recorded during machining the work pieces in order to control the temperature of cutting process.Theoretically, empirical equations for temperature of cutting tool and surface roughness of the work piece have been discovered. By using Genetic Algorithm technique these equations have been used to find the optimum of cutting parameters spindle speed, feed rate and depth of cut.The optimum values that obtained by using Genetic Algorithm which achieve sustainable cutting were spindle speed 588.96 rpm, depth of cut 0.50 mm and feed rate 64.55 mm/min in order to have the optimum of surface roughness in low cutting temperature.

“…The study exposes that the surface roughness is directly influenced by the spindle speed and feed rate. It is observed that the surface roughness increases with increased feed rate and is higher at lower speeds and vice versa for all feed rates [13]. It was experimentally determined that material removal rate in CNC turning process is influenced by cutting speed and depth of cut.…”

In this article, vacuum pressure for holding thin walled cylindrical object in vacuum clamping system on a computer numerical control machine (CNC) is studied. In this work, thin walled cylindrical object in vacuum clamping system is designed and different parameters for the vacuum clamping system are calculated. CNC rolling and flow farming machines are being employed for the thin wall and complicated objects. It is very challenging to make various thickness thin walled objects at high precision with help of jig and fixture at large scale. A lot of time is consumed for non-operational activities and skilled operator is required. In this work, this problem is resolved by replacing the machines built with 3-jaws hydraulic chucks with traditional made flexible clamping system. It would increase production rate and accuracy of object as compared to other conventional manufacturing processes. Designing imprecision may lead to process tolerance that caused to enhance manufacturing expenditure. In this work, optimum cutting parameters: feed rate, surface roughness and depth of cut of vacuum clamping system are deliberated. The main focus of this research is to design alternate clamping system for holding thin walled work piece with variable thickness and to save time, men power and raw material.
