Using basic magnesium carbonate (Mg(OH)2·4MgCO3·6H2O) and SiO2 as raw materials, forsterite (Mg2SiO4) was prepared by solid state synthesis process.
In the later experiment, MgO should be added to the raw materials mixtures for further reaction.

Knowing temperatures at the tool-chip interface is extremely important to optimize the machining condition and to improve the machining performance, furthermore to design high performance materials.
Some additives are contained in novel materials to control the tool wear rate and improve the cutting performance.
Therefore, the indexable insert developed can be utilized for optimizing the cutting condition, improving the cutting performance and designing materials with high-machinability.
