“…1 Generally, the insert which suffers from violently cutting force, high cutting heat, and severe wear is the key factor in metal cutting because of the direct contact with the workpiece; hence, proper insert selection is a very important issue during metal cutting process. In today’s metalworking industry, many types of materials, such as high-carbon steel, carbide, 2 ceramics, 3 and diamonds and CBN 4 with different coatings 5 are used for cutting tools. In addition, tools with various shapes are also developed to meet the requirements in wide range of conditions, 6 which made the tool selection a multi-criteria decision-making problem in the presence of various selection criteria and a set of possible alternatives.…”

Tool selection is a multi-criteria decision-making problem in the presence of various selection criteria and a set of alternatives, but previous works are limited to evaluating the tools within the workshop tool library. To intelligently select proper inserts across suppliers under the Internet environment, an insert data format based on ISO 513 was established, and a framework was then designed to obtain a set of alternatives from different suppliers based on fuzzy intervals. Then, knowledge was described with convenient language and the simple membership function to build an intelligent system, which would infer the matching degree of insert characteristics to the machining conditions. Furthermore, analytic hierarchy process was applied to sort the alternatives. Finally, the case study shows that compared with previous works and machinists, this work not only obtains a set of alternatives from all suppliers who uploaded their product data with the designed format but comprehensively evaluates the insert (take finishing low-carbon steel as an example, both cemented carbide and cermet are recommended, the nose radius reduces 25%, the environmental index increases 25%, while the rake reduces 11.25%, when compared with machinists who tend to select the larger rake angle foe finishing). A platform was also developed based on Visual Studio 2015 and SQL Server 2012 to improve selection efficiency for inexperienced CNC operators, purchasers, and vendors.

“…Cui et al 5 established the tool material damage model, proposed the critical condition of tool damage, and revealed the tool failure mechanism under thermo-mechanical load. Cheng et al 6 analyzed the failure mechanism of cemented carbide tool under cyclic impact load and the crack propagation law of tool material by milling 508 steel. The tool impact damage model was established, and the impact fracture limit condition of tool material was determined.…”

As a typical aerospace difficult-to-machine material, tool failure in milling titanium alloy Ti6Al4V will reduce the stability of the milling process and affect the surface quality of the workpiece. Aiming at the fact that cemented carbide tools are prone to wear failure and breakage failure in milling titanium alloy, a safe tool failure boundary map is provided to ensure that the tools will not occur failure with the cutting parameters selected in the safe area during the prediction time. Based on the processing characteristics of Ti6Al4V, the failure boundary map mainly considers three forms of tool failure: flank wear, rake wear, and cutting edge breakage. By revealing the three failure mechanisms, the failure analytical model is established and the failure boundary map is obtained. Compared with the experimental results, it has good consistency, and the research results can provide a reference for the field of titanium alloy cutting process.
