A leveling adjustment device attached to a machine tool with supporting foot portions being adjusted manually to change a height, which includes a sensing module and a microcontroller unit. The sensing module senses the machine tool for inclined extents in two directions perpendicular to each other and then generates a sensed data. The microcontroller unit receives the sensed data and provides a graphical operation interface with first blanks and second blanks. The first blanks are used to fill with a length and width data of the machine tool while the second blanks are used to fill with a coordinate data corresponding to each of the supporting foot portions. The microcontroller unit calculates an adjustment sequence and an adjustment value corresponding to each of the supporting foot portions based on the data in the first and second blanks in conjunction with the sensed data and then displays in the graphical operation interface.

A cutting tool, a turning machine including the cutting tool, and an associated method are provided. The cutting tool includes a tool, a cutting head, a strain gauge, and an accelerometer. The cutting head is located at the tool bar and has a cutting edge. The strain gauge measures strain at the tool bar. The accelerometer measures acceleration at the tool bar or the cutting head. Deflection of the cutting edge is estimated based on output from the strain gauge and the accelerometer. In some embodiments, the accelerometer is arranged close to the cutting edge, while the strain gauge is arranged where the tool bar is susceptible to the largest strain. In some embodiments, low frequency vibrations of the cutting edge are estimated based on measured strain, high frequency vibrations are estimated based on measured acceleration, and medium frequency vibrations are estimated based on output from both sensor types.

Disclosed are systems and devices for controlling the closing of a door. A head unit is to be installed in a doorjamb, comprising a chamber filled at least in part with a shear thickening fluid. A piston is connected to a cap and configured to exert pressure against the shear thickening fluid in response to a force applied to the cap. The systems and devices provide an adjustable design that resists door slamming and aggressive closure, serving as a safety device as well as noise, damage and pet control around doors (preventing closure if desired). An install kit provides exact location, depth control and guide to place over the head unit to tap it into place with a hammer.

In an inspection master, an upper-surface oblique reference portion opened obliquely upward is provided on an upper surface of a master main body including the upper surface and a peripheral surface. In an inspection master, a peripheral-surface oblique reference portion opened obliquely upward is provided on a peripheral surface of a master main body including an upper surface and the peripheral surface. In either of those cases, an upper-surface vertical reference portion opened vertically can be provided on the upper surface, and a peripheral-surface lateral reference portion opened laterally can be provided on the peripheral surface. Further, a reference ball for use in obtaining an inclination angle of the master main body inclined during accuracy inspection for a five-axis processing machine is provided at a center portion of the upper surface.

A laser projection device with compact frame is provided, as is a corresponding frame or mount for one or more laser projection devices. In one embodiment the frame or mount includes a coupling interface that permits multiple coupling positions with respect to a laser projection device, such as at 90 degree intervals.

Provided is a servo controller that can prevent an unnecessary cut from being generated during oscillation machining. A servo controller which controls a machine tool 10 that turns a workpiece W by cooperative operation of a plurality of axes includes: an oscillation command generating unit 23 that generates an oscillation command for causing the workpiece W and the tool 11 to relatively oscillate; a deviation deducting unit 31, 241 that applies the oscillation command to a position deviation based on a moving command for causing the workpiece W and the tool 11 to relatively move, and deducts a steady-state position deviation; and a learning control unit 27 that calculates a compensation amount from a position deviation based on the moving command after deducting the steady-state position deviation.

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.

A numerical-control machine tool is provided that includes a tool-holder head which is provided with a tool-holder spindle and is capable of rotating/tilting the tool-holder spindle about two different rotation axes inclined to one another; a movable supporting structure that supports the tool-holder head and is provided with moving members adapted to move the tool-holder head in the space around the piece to be machined, during machining of the piece; one or more inclinometer microsensors that are located on the movable supporting structure of the machine, next to the tool-holder head, and are adapted to measure/determine the tilt of the element on which the same sensors are mounted, relative to a reference inertial plane immobile in the space; and an electronic control device that commands the various moving members of the movable supporting structure and of the tool-holder head, that is electronically connected to the one or more inclinometer microsensors and is adapted to control, during machining of the piece, the different moving members of the movable supporting structure and of the tool-holder head based on the signals arriving from the inclinometer microsensor(s), so as to correct the spatial position and/or the orientation of the tool-holder spindle based on the signals arriving from the one or more inclinometer microsensors.
