▎ 摘　　要

The present investigation describes the enhancement of the cutting tool properties by advancing the rake surface with micro texturing in the field of machining. A spiral triangular micro texture cutting tool is to be investigated the machining aspect of Ti grade 2. Utilizing laser surface texturing a spiral triangular micro texture is fabricated on the rake face of tungsten carbide chemical vapour deposition (CVD) coated insert. An investigation was carried out with different types of tool inserts like plain tool (PT), triangle micro texture tool (TT), and triangle texture tool with solid lubricant (TTS). The impact of micro texturing is characterized by machining of titanium grade 2 in a dry environment in turning operation. Experiments are designed and steered using L-27 orthogonal layout with 3-level cutting velocity, feed, and type of tool insert. Using taguchi optimization analysis of variance (ANOVA) has been carried out to find the highest contributing factor. Cutting temperature, surface roughness (R-a) and tool wear are monitored with an infrared thermometer and optical microscope, and Macroscale chip morphology is inspected. The outcomes have been explored results that cutting velocity and micro texture play an important role in increasing or decreasing the response parameter. Temperature, tool wear, and surface roughness analysis have been done. It is found that triangle micro texture tool with solid lubricant reduces the output parameters. Macroscale image chips have been analyzed that longest and snarled ribbon type of chips are formed.
