A method for checking positioning accuracy of a CNC machine with a machine tool head and a machine table using an x, y, z coordinate system, the method comprising:

Method and system for checking positioning accuracy of a CNC machine

A numerically controlled machine tool, and method for control thereof, to display virtual two-dimensional future positions to be adopted by a workpiece and by the machine tool in a pre-set predictive time window. The system and method calculate target coordinate values defining positions of the tool along axes of the machine tool on the basis of a machining program. While machining is in progress, a processor receives the calculated target coordinate values to generate and display image data on the basis of the target coordinate values and of stored mathematical models of the machine, of the workpiece, and of the tool.

Predictive control and virtual display system for a numerically controlled machine tool

A feeler device comprises a support structure in which a movable assembly is movably mounted along three axes, the movable assembly carrying at one end a feeler member. The movable assembly is suspended in the support structure by means of laminar elements which have respective slots of spiral, preferably logarithmic, form.
