Abstract - The output from a computer numerical control machine tool can be increased to a large extent by using a tool life management system if and when the tool life management system is applied or implemented properly. When considering whether the system is right for the given applications, we consider that the ultimate goal of any tool life management system is to keep all tool maintenance offline. Tool maintenance includes any task done to keep tools cutting on size (measuring work pieces and sizing tools) as well as any task performed when tools get dull (tool/insert replacement, re-measuring program zero, trial machining, and more). By doing tool maintenance offline, the task must be done in conjunction with the production run, while the machine is in cycle. The design of machine should be done in such a way that a tool can easily and safely removed and replaced while performing the maintenance of the machine and the machine is running so as to neglect the unproductive time.
uniformly managed or organized. Tool life management in general deals with two major parts which include documentation and transaction data; where the documentation handles the information required for trouble and impactful production processes. Tool life management provides flexibility in its working system by its ability of modifying the feeds and cutting speeds based on cutting tool material required for metal working processes. Thus due to this several functions such as processing, modifying, documenting ,managing etc. together as a whole can be handled through tool life management. 1.1 METHODOLOGY

With a proper, effective and efficient application, tool life management systems can increase the output from CNC machine tool to a great extent. While considering the fact that whether the system is suitable for various applications of tool life management systems, it is quite essential as well as necessary to keep all tool maintenances offline. Tool maintenances include the tasks of keeping the cutting size of tool within its range/limit, as well as it includes tasks which are required when tools get dull. By performing tool maintenance offline, the tasks are thus done in conjunction with the production run, while the machine is in cycle. Also we need to consider a fact that tool life management in many applications could add a lot of production run time. For the matter of fact to avoid such circumstances many CNC machines, especially their turning centers are kept down while the dull cutting tools are being replaced. Thus if the tool maintenance are kept away from affecting the production run time, the jobs would get completed much faster and also the cycle time would be reduced visibly. Also tool life management do play a vital role in metal working processes, so that the information regarding the tool can be Š 2017, IRJET

The tool life is the duration of actual cutting time after which the tool is no longer usable. There are many ways of defining the tool life and the common way of quantifying the end of a tool life is by a limit on the maximum acceptable flank wear. With a good application and when properly applied, a tool life management system can dramatically increase for a CNC machine tool. Tool life management includes any task done to keep
