A technique provides for wireless control of a machine tool, e.g. a portable machine tool used on-site. According to an embodiment, a motor is connected with a tool post assembly via a gearbox. The motor is coupled with a machine controller, and the tool post assembly is mounted proximate an object to be machined. For example, the object may be machined via a cutting tool mounted to a cutter post of the tool post assembly. The machine controller operates to control movement of the cutter post along a desired axis during the cutting operation. The machine controller and thus the cutting operation, however, are controlled wirelessly according to control instructions provided via a control device, e.g. a handheld control device, which is placed in wireless communication with the machine controller.
