A device for determining an approach of a tool to a workpiece in a machine tool with internal cooling supply includes a measuring arrangement, having a measuring graduation arranged in a rotationally fixed manner on a shaft and at least one position sensor arranged in a fixed manner relative to the shaft, and a data processor. The position sensor is adapted to scan the measuring graduation and to generate position values therefrom that indicate a position of the shaft. The position values are fed to the data processor, which, by evaluating a progression of the position values when the tool approaches the workpiece, determines that the tool is located in an approach area relative to the workpiece, and signals, by an approach signal, when the tool reaches an approach position relative to the workpiece, in which the tool is close to the workpiece without touching it.

An advanced jig for manufacturing a firearm lower receiver can include an adapter, a guide plate, a front support, a buffer support, a buffer mounting screw and at least one carriage with at least one locating pin. A guide plate can be in a location above the fire control cavity of a lower receiver and can be mounted to the carriage(s) in conjunction with a rotary power tool adapter. The jig can be a universal fitment. The jig can include a bearing to support a rotary tool and can be constructed and arranged to provide for use of at least one guiding feature to facilitate in the guidance of the rotary tool without placing the rotary tool in direct contact with any of a plurality of guidance features for firearm lower receiver manufacturing. A removable locating pin can be situated in a location along the front takedown pin hole of a firearm receiver that is for firearm lower receiver manufacturing.

The present disclosure is directed to calibrating position detection for a tool. The tool can use a sensor to detect a first value of a parameter. The tool can use a motor to extend the working member of the tool towards a working surface. The tool can include a base. The tool can detect, with the working member in contact with the working service, a second value of the parameter. The tool can determine a z-axis position of the working member relative to the working surface.

Systems and methods of the present disclosure relate generally to facilitate performing a task on a surface such as woodworking or printing. More specifically, in some embodiments, the present disclosure relates to mapping the surface of the material and determining the precise location of a tool in reference to the surface of a material. Some embodiments relate to obtaining and relating a design with the map of the material or displaying the current position of the tool on a display device. In some embodiments, the present disclosure facilitates adjusting, moving or auto-correcting the tool along a predetermined path such as, e.g., a cutting or drawing path. In some embodiments, the reference location may correspond to a design or plan obtained from obtained via an online design store

The invention relates to a system of a method for controlling a machine tool, and a workpiece, in particular a milling blank, and the method for machining this workpiece, said machine tool comprising a robot arm movable in at least 2, in particular at least 3 spatial axes in a range of motion, said robot arm carrying, guiding and moving at least one workpiece, possibly by means of a workpiece holder, with a control unit for controlling the machine tool. The machine tool (62) comprises a sensor, in particular a spatially fixed optical sensor or is assigned said sensor, whose detection range (66) at least partially overlaps the range of motion. The workpiece (10) comprises a change in geometry, in particular a hole (12), is moved in the detection range (66) by the robot arm (70), and upon detection of the hole (12) by the sensor the control unit determines a reference point, reference axis and/or reference surface for controlling the machine tool (62).
