A temperature of a portion of which the temperature is difficult to directly measure is accurately estimated in a simple method. In S1, information about a coolant discharging/stopping state is obtained. As the information about the coolant discharging/stopping state, a flag is used such that the flag represents 1 for the discharging state and the flag represents 0 for the stopping state. Next, in S2, temperature data is obtained from temperature sensors provided in components of a machine tool, a machining space, and a coolant tank. Next, in S3, lag process is performed for the coolant discharging/stopping state flag, and coefficients for measured temperatures of the coolant and the structure are calculated. Next, in S4, the measured temperatures are multiplied by the coefficients, and an estimated temperature of a portion to which the temperature sensor is not attached is calculated.

The present application relates to a machining assembly comprising an effector intended to be mounted on a robot with multiple degrees of freedom, in which invention the mounting of the motor spindle relative to the intermediate supports and frame of the effector allows a numerically controlled movement along three axes X, Y, Z of a trihedron, the effector bearing on the piece to be machined or on the surrounding tools by means of a ball joint at the foot end of the effector. Since the effector bears on the piece to be machined or on the surrounding tools it is possible to create local stiffness and to obtain the precision required to guarantee the quality of the machining process.

A method for determining locations of supporting points for a machine tool is proposed. Multiple test coordinate sets in relation to the machine tool are used in cooperation with corresponding deformation index values for multiple components of the machine tool to obtain a deformation index equation that relates to assessed deformation of the components in response to different coordinates for the supporting points. The deformation index equation is used to acquire an optimal coordinate set for the supporting points.
