| 500 ## - GENERAL NOTE | |
| General note | Mechanical machining is one of the commonly employed techniques in manufacturing<br/>industries, given several other production processes. Due to their high hardness and specific<br/>strength at elevated temperatures, machining of titanium alloys is considered very difficult.<br/>Considering the machinability challenges of these alloys, tool wear and energy consumption<br/>during machining remain the main concern for achieving sustainable machining goals. Since<br/>the tool wear is linked to the product quality and cost of machining, therefore, a comprehensive<br/>wear map approach based on experimental cutting test is very useful for monitoring the tool<br/>life. Whereas energy consumption in a machining process is associated with the machine tool<br/>efficiency, cost of energy and carbon footprints, the evaluation of energy consumption using<br/>energy maps is therefore very helpful in improving machining performances. Thus, improving<br/>the tool life and minimizing energy consumption are the prime contributors in achieving<br/>economic and energy-efficient benefits of production.<br/>The research presented here first studied the tool wear progression in turning of titanium alloy<br/>(Ti6Al4V) and then the effect of progressive tool wear on specific cutting energy was further<br/>analyzed for the development of the energy map. Tool Wear and Specific Cutting Energy maps<br/>were developed for turning of Ti6Al4V alloy by performing a series of unified cutting tests.<br/>The wear map developed plots the wear rate on a feed Vs. cutting speed grid and have identified<br/>regions of low, moderate and high tool wear rates. Interestingly, a high wear zone (avoidance<br/>region) at the interface of low and moderate tool wear appeared on the wear map. Analogous<br/>to the wear map, regions of low, moderate and high energy consumption were also identified<br/>on the energy map. The two maps developed thus corresponds to the cutting conditions<br/>employed in turning operation highlighting high energy and wear regions that should be<br/>avoided during the cutting process. Although wear maps have been presented for a variety of<br/>materials including Ti6Al4V alloys, this research work presents a wear map together with<br/>energy map for turning Ti6Al4V alloy. The energy map plots the Specific Cutting Energy<br/>(SCE) utilized at the tooltip against the cutting condition used in the turning process. The<br/>energy map methodology was used for the selection of optimal cutting condition that will<br/>minimize the energy consumption of the machine tool.<br/>The study of the tool chip contact length and the chip formation analysis is a way to understand<br/>the interactions and mechanics of a machining process. The analysis of the tool’s flank surface<br/>revealed that the chemical interaction between the tool and workpiece is the main cause for<br/>high tool wear and energy consumption as titanium alloys are well known for its severe<br/>ix<br/>reactiveness at higher cutting temperatures. Since machining of titanium alloys is challenging<br/>because of the inherent properties of the material, therefore, this research was focused on the<br/>study of energy consumption and tool wear analysis to achieve economic and sustainable goals<br/>of production engineering. The energy and wear maps thus developed are also very useful on<br/>the shop floor and provide for the choice of cutting conditions to produce parts from Ti6Al4V<br/>alloys, together with less damage to cutting tools and efficient use of machine tools. |
