Up to 75% of the overall geometrical errors of machined work pieces can be induced by the effects of temperatures [1,2].
Fig.1 shows the schematic diagram of the research object, a 4-axes horizontal machine tool.

Ti3AlC2, as a member of the family of ternary carbides and nitrides M3AX2 (where M is a
transition metal, A is an A-group element, and X is either C or N) that possess an unusual combination
of mechanical, electrical, thermal and chemical properties [1], has been attracted attention in the last
few years.
The bulk polycrystalline Ti3AlC2 has a low Vickers hardness, low thermal expansion coefficient, high modulus, high compressive strength, excellent resistances to oxidation and thermal shock, unusual brittle-to- ductile character and damage tolerance, readily machinability, and particularly a good electric and thermal conductivity [1].
emphasized that the fracture strength, even if the lowest 808 MPa, is higher considerably than either of the polycrystal Ti3AlC2 bulk (∼ 375 MPa [1]) and general Cu-alloys (400 ∼ 600 MPa).
