ABSTRACT:
A CNC machine tool deflection compensation system intergrated in a CNC machine tool Controller for providing continuous, accurate, real-time compensation for unintended and/or undesired axis coordinate deflections from a preprogrammed path of tool movement in a coordinate plane, so as to ensure that the tool remains on its programmed path irrespective of such deflections capable of continuously detecting, in real-time, the presence, magnitude an rate of change of such undesired deflections and simulataneoulsy genereating instrtuctions to initiate equal and opposite deflections at the same rate of change, thereby ensuring that the tool remains on its preprogrammed path irrespective of the inherently occuring undesired deflection and/or the precipitating causes(s) thereof. The algorithms empolyed provide for automatic gouge avoidance protection and/or relocation of the tool to safe positions when necessary. All foregoing features are built into the CNC Controller at the outset, thus obviating the need for intervention by the machining operator.
