A machining tool thermal compensation system based on an aggregation model includes a calculating module and a processing module. The calculating module executes a first thermal compensation model and a second thermal compensation model. The first thermal compensation model is only related to motor temperature change and the second thermal compensation model is only related to environmental temperature change. The processing module executes an aggregation model based on Kalman filter. The calculating module inputs the motor temperature of a target machining tool at a time point into the first thermal compensation model to generate a first compensation value and inputs the environmental temperature of the target machining tool at this time point into the second thermal compensation model to generate a second compensation value. The processing module executes the aggregation model according to the two compensation values to generate a modified compensation value of this time point.

An apparatus for active contact force control can have an upper flange on which to mount a production tool. The apparatus can be mounted, via a lower flange, on a multi-axis machine to obtain spatial motion together with the corresponding production tool. The apparatus can comprise a housing inside which can be a linear actuator connected to guides. Mechanical connection between a ball screw and the upper flange can contain a force sensor and at least one spherical joint. The connection between the spherical joint and the upper flange can be formed using a mechanical dissipative element made of elastic dissipative elements and a disc plate positioned between the elastic dissipative elements.
