A machine tool for carrying out operations on a part includes a longitudinal rail, a transverse arm, a module for connection between the transverse arm and the longitudinal rail, the module being fitted in translation on the longitudinal rail, a tool which is supported by the transverse arm, and a retention unit which is arranged at one end of the transverse arm, and includes at least one sucker. The machine tool has an assembly configurationin which the retention unit and the tool are positioned respectively on both sides of the longitudinal rail, such that the tool is fitted cantilevered relative to the longitudinal rail. This provides the machine tool with great polyvalence, in that it makes it possible to carry out operations in areas which in particular have significant curvatures, which are difficult to access, or which are unsuitable for securing of the sucker(s) of the retention unit.

A method for pushing, with a force a tool at the end of an articulated arm against a surface with a normal, including the steps of: positioning the tool against the surface; applying an increasing force to the tool until reaching a value, corresponding to a fraction of the force, the value of the applied force being monitored; measuring the orientation of the tool with respect to the normal, after having reached the force value; and redirecting the tool so as to recover its initial orientation with respect to the normal. Iteration is carried out to proceed, by repetition of steps to, while progressively increasing the force at each iteration, and until reaching the force value, the increase increment between two successive steps being smaller than a determined value.

A drilling apparatus includes: a drill rotatable about a center axis and capable of advancing and retracting along the axis; and a pressing unit for pressing a work in an advancing direction of the drill. The drilling apparatus advances the drill while rotating the drill about the center axis to form a hole in the work, in a state in which the work is pressed by the pressing unit. A pressing force applied on the work by the pressing unit is set to a predetermined pressing force based on machining reaction applied to the drill from the work during drilling and the pressing force causing deformation of the work in the advancing direction of the drill. The predetermined pressing force can suppress deformation of the work and displacement of the drill due to the machining reaction. The machining reaction and the pressing force are calculated beforehand in a drilling test.

An auto-feeding permanent magnet drill comprising a first permanent magnet capable of being removeably coupled to a magnetic material. A coupler plate couples to the first permanent magnet. A drill frame couples to the coupler plate, the coupler plate providing an interface to couple the first permanent magnet to the frame. User interfaces are provided to enable control for powering the drill, enabling a drill or cutter bit auto-feed feature, enabling a lubrication system and enabling a mechanical adjustment system. An electric drill is coupled to the frame, the electric drill coupled to the auto-feed feature and electronically coupled to the user interfaces. A lubrication reservoir couples to a second permanent magnet capable of coupling the lubrication reservoir to a magnetic material or work surface. A flexible distribution tube delivers lubricant from the lubrication reservoir to a nozzle, the nozzle oriented towards the cutting surface and capable of distributing lubricating fluid to the cutting surface or rotating drill bit components during a drilling operation.

A drill guide device comprising a speed detection device for measuring speed of a drill bit used by the device for drilling an object surface during a hand drilling operation; a force detection device for measuring force applied by the drill bit on the object during the hand drilling operation; an alignment detection device for detecting alignment of the drill bit with respect to the object surface during the hand drilling operation; a user interface connected to the speed detection device, the force detection device and the alignment detection device adapted to communicate to a user information related to the speed, the force and the alignment of the drill bit during the hand drilling operation.

An intelligent electric drill includes a case which has an MCU control unit, a drive unit, a power unit, and a data unit. The MCU control unit controls the power, speed, and torque of the drive unit. A mechanical speed mode recognition module group is electrically connected to the MCU control unit and includes a speed mode recognition electronic module and a plastic speed mode module within the case. The mechanical speed mode recognition module group determines the switching position of the plastic speed mode module, and the speed mode recognition electronic module inputs the determined signal to the MCU control unit. This allows users to automatically recognize the positions of mechanical speed mode and function mode while driving with the electric drill. Users can drive with accurate and appropriate power, achieving precise output of speed, torque, and workload.
