Because the thermal conductivity of titanium is small, the heat generated during cutting cannot be dissipated and will be stored in the tool, so the wear on the tool will increase.
Because of the high chemical activity, when the cutting speed increases, more cutting heat will occur and the temperature of the cutting part will increase, so the activity will increase and the wear on the tool will increase.
Because of continuous deformation, chips are generated, the cutting resistance of the cutting edge becomes larger, and the tip is prone to collapse and wear.
Because the modulus of elasticity is small, the processed material is likely to be greatly deformed during cutting, especially when processing thin workpieces, the processing accuracy and chatter will be reduced.
When cutting or cutting with a tool with wear, fine chips will appear, high temperature may sometimes cause the chips to ignite.
