However, stainless steel alloys are difficult-to-machining materials; currently the general tools used to manufacture stainless steel usually fail to meet the requirement, even the tools made by cubic boron nitride or ceramics are unable, due to its own mechanical physical properties far from the requirements.
Under the same cutting condition, we can measure the cutting performance of different tool materials through comparing their durability.
While cutting different workpiece materials with the same cutting tool material, we can use durability to measure the machine ability of different workpiece materials.

However, in cases where an inflammable liquid has been used, enough unburned material may remain absorbed in the fire debris to be detected and identified by certain analytical techniques.
The longer the floor carrier attached with burned gasoline residues material exposed in the air, the harder the detection of the gasoline burning residual material.
