Definition

Thermal errors are the geometric errors that a piece suffered during its manufacturing processes as a consequence of temperature changes.

Theory and Application

Introduction

Temperature changes produce changes in the size of the materials. Uniform temperature changes of the manufacturing system, accompanied by uniform temperature change of the part, would not produce change in the dimensions of the part when taken to the reference measuring temperature, provided that the machines and the part are built in the same single material. But temperature changes are never uniformly distributed along the machine and the part, and the temperature gradients can give rise to large errors in the parts produced.

Ambient temperature changes are one of the reasons for appearance of temperature gradients in the machine and part, and in fact, when the maximum accuracy has to be obtained, the machines are located in temperature-controlled rooms or enclosures. Nevertheless, in more conventional...
