If the thermal deformation pre-compensation module has additional deformation data, it is superimposed on the corresponding axis error to calculate the compensation amount. For axes with high precision requirements, a compensation coefficient can be set, such as 1.2 times for the Z axis, to strengthen the correction force, ensure that the error is reset to zero in real time, and maintain processing accuracy. Mineral casting materials are composite materials made of mineral particles as the main aggregate, with binders such as resin or cement, which are mixed, cast, and cured.
