A device for determining a penetration depth in a drilled hole which is drilled into a workpiece (W) from a workpiece surface (WO) with a drill of a drilling machine. The device contains at least one light source for projecting a light field is provided onto a workpiece (W) to be processed by the drilling machine. The light source is positioned with respect to the drilling machine in such a way that a centre axis (L) of the light source runs at an angle (a) with respect to a central axis (L) of the drilling machine, and at least a first blocking element for partially covering the light source is provided, said blocking element forming a reference on the light field.

A length-measuring device includes a scale and a mounting element. The mounting element has a first fastening portion by which the mounting element is stationarily attached to the scale and a second fastening portion configured to be stationarily attached to a support. An arrangement of a plurality of flexible struts is provided between the first fastening portion and the second fastening portion which, through flexure, allows the first fastening portion to move relative to the second fastening portion perpendicularly to the longitudinal direction. The arrangement of struts is configured to compensate for a flexure-induced change in length of the struts in such a way that no movement will result from the flexure-induced change in length between the first fastening portion and the second fastening portion in the longitudinal direction.

Disclosed is a method for machining a component, comprising: installing the component on a fixture, causing a medium of the fixture to solidify to encase a first portion of the component, applying a toolset to a second portion of the component that is outside of the solidified medium, and subsequent to applying the toolset, extracting the component from the fixture when the medium is in one of a liquid state or a semi-liquid state, where the medium has a melting-point temperature that is less than 500 degrees Fahrenheit. Disclosed is a fixture for machining a component, comprising: a medium configured to encase a first portion of the component when the medium is in a solidified state, and a toolset configured to be applied to a second portion of the component that is outside of the solidified medium, the medium having a melting-point temperature that is less than 500 degrees Fahrenheit.

According to an exemplary embodiment of the present disclosure, a method of setting up a work piece based on a vision is present. The method of setting up a work piece based on a vision comprises: calculating a start point of a work piece from the image of a work piece within a vision screen formed by a camera; capturing an image when a tool is captured in the vision screen; and calculating an offset value of the tool from the captured image.

An improved jig for manufacturing a firearm lower receiver is comprised of a power tool mount; an adapter; a guide plate with plate screws; a rear support with mounting screws; a front support; and at least one of a carriages with at least one locating pin. A guide plate is disposed below the top surface of a lower receiver in conjunction with an adapter. The jig is a universal fitment and includes a bearing to support a rotary tool and at least one guiding feature can be used to facilitate in the guidance of the rotary tool without placing the rotary tool in direct contact with any of the guidance features. A removable locating pin is situated a long the front and rear takedown pin holes of a firearm receiver that is not threaded and is provided with at least one of a pull, string or other handle.

A tool for machining an object including a first part including a rotatable member that is rotatable to cause rotation of a machine tool, a second part, a joint coupling the first part and the second part to enable relative movement between the first part and the second part, and a sensor to sense an object to be machined.

A router guide is provided. The device includes a planar body having a first elongated opening and a second elongated opening therethrough. The first elongated opening intersects the second elongated opening perpendicularly. A circular opening having a diameter greater than the first and second openings, wherein the circular opening is disposed through the planar body at an intersection of the first and second elongated openings, such that the circular opening is dimensioned to receive a router bit therethrough. In some embodiments, a plurality of apertures is disposed through the planar body, wherein the plurality of apertures is disposed in a pair of colinear rows disposed parallel to each lateral edge of the planar body.

An estimating device estimating a rotary axis position of a workpiece includes first and second position acquisition units acquiring tool positions in first and second directions, a load acquisition unit acquiring first and second directional loads of the tool in the first and second directions, a determination unit determining whether or not the first and second directional loads each are a threshold or less, a turning control unit performing a lathe turning on the workpiece until the first directional load becomes the threshold or less and thereafter performing a lathe turning thereon until the second directional load becomes the threshold or less, and an estimating unit estimating the rotary axis position based on a first directional position of the tool when the first directional load has become the threshold or less, and a second directional position thereof when the second directional load has become the threshold or less.
