102 ISCAR LOOKING FOR THE OPTIMUM TOOLAn ideal cutting tool should provide maximum productivity in combination with reasonable and stable tool life. To determine the appropriate solution, tool manufacturers develop advanced cutting geometries and new cutting material grades that enable reliable cutting at high metal removal rates (MRR) for diverse types of machining data. As the tool is expected to enable effective machining of different engineering materials, the geometry and the grades should be optimized accordingly.Decreasing machine downtime is one more way to reduce production costs. The appropriate waymarks, which relate to tool attributes such as ensuring tool availability and minimizing setup time, can greatly contribute to the solution. Tool delivery is crucial for replacing %u201csuitable%u201d with %u201coptimal%u201d.By saying, %u201cthe best tool is the one you have on hand%u201d, one can understand important metalworking principles, making the ideal tool readily accessible.In a perfect world, the ideal tool facilitates machining various workpiece shapes on long- or short-reach applications without loss of performance. Tool customizing is an additional parameter for finding the optimal solution.Advanced machines are expected to integrate optimal machining strategies. These strategies are planned, programmed, checked, and verified in a virtual environment of computer-assisted engineering (CAE) systems well before the process begins on a CNC machine. Therefore, the right tool should have an appropriate virtual component, a digital twin, to be embedded in CAE systems.NEOITA %u2013 ISCAR%u2019s Tool AdvisorISCAR%u2019s Tool Advisor, known as NEOITA, is a parametric search engine that %u201cthinks%u201d like a process engineer and allows finding the right tool based on the accumulated knowledge of best practice worldwide. This system enables searching for an optimal tool intended for a specific machining operation. With the use of engineering analysis and expert knowledge, NEOITA generates a set of more efficient solutions with suitable cutting data, calculates metal removal rate (MRR), machining power, facilitates direct access to the e-Catalog, insert wear detection, and more.A responsive design application has brought NEOITA to handheld devices. Through cloud-based technology, the NEOITA is available 24/7 and in multiple languagesFig. 15.1. NEOITA, the ISCAR Tool Advisor expert system available for mobile phone use
