An assembly for controlling waste material during a hybrid subtractive and additive manufacturing process is disclosed, including a machining tool held in a holder, a shroud disposed around the machining tool, and one or more ports configured to create a negative pressure within the shroud. A method of constraining waste material during a hybrid subtractive and additive manufacturing process of a part includes adding an amount of material to a part being additively manufactured, transforming the amount of material that was added, manipulating a tool to machine a portion of the part being additively manufactured and generating a waste material, sealing a portion of the tool and covering a portion of the part with a shroud, and applying a negative pressure to create an airflow to prevent the waste material from exiting the shroud.

This unique and novel invention provides a custom data removal jig used to reliably, efficiently, and cost-effectively remove data from a handheld mobile computing device (“PC device”). The data removal jig comprises an open-box structure which provides one or more alignment features to assist with properly inserting the PC device within the data removal jig. Additionally, a pilot hole is provided by the securement structure. Once the PC device is inserted into the data removal jig, the pilot hole is substantially centered above the integrated flash memory chip on the particular PC device's motherboard which the data removal jig has been customized to accommodate. A power drill is used to precisely penetrate the PC device via the pilot hole and substantially isolate the damage to the integrated flash memory chip. Additionally, the securement structure also provides one or more braces that assist with restraining movement of the securement structure during the data removal process.

A machine tool is provided with a main shaft configured to have a tool fitted to a distal end portion thereof, a tool magazine for holding a plurality of tools, a tool exchanging arm for exchanging tools between the tool magazine and the rotary main shaft, and a table for attaching a workpiece, wherein the machine tool machines the workpiece by causing the main shaft and the table to move relative to one another in accordance with a machining program, and wherein the machine tool: is provided with an image capturing device for capturing an image of the tool fitted to a tool holder, and an interference checking device which uses the machining program, and shape data relating to the workpiece, the tool, and the machine tool to simulate machining before machining is carried out, to check for the presence or absence of interference between at least the tool and the workpiece; and acquires the shape data relating to the tool from the interference checking device, generates a two-dimensional tool model from the acquired shape data relating to the tool, compares the two-dimensional tool model with an image of the tool captured by the image capturing device, and determines that the tool is invalid if an amount of displacement between the two-dimensional tool model and the image data is equal to or greater than a prescribed threshold.

Provided is a machine tool including: an image acquiring unit that acquires an image of an imaging target; a movement mechanism that relatively moves the imaging target and the image acquiring unit; and a control unit, wherein the movement mechanism relatively moves the imaging target and the image acquiring unit by a known distance in an imaging direction of the image acquiring unit or in a direction substantially perpendicular to the imaging direction, and the image acquiring unit acquires images of the imaging target before and after the movement, and the control unit calculates a distance between the image acquiring unit and the imaging target in the imaging direction based on a movement distance or a length measured in the two acquired images. This enables distance measurement to be performed in a short time without making contact with an object to be measured.

A machine tool includes a headstock that holds a workpiece, a tool post that is movable in a first axis direction parallel to a workpiece rotation axis and in a second axis direction orthogonal to the first axis and holds a tool, an in-machine robot, an opening for communicating the inside and the outside of a working chamber, and a door that opens and closes the opening. The robot includes a root joint fixed in the working chamber and a link unit positioned on a distal end side of the root joint. The root joint is a linear-motion joint extendable in a direction orthogonal to the workpiece rotation axis, and is a linear-motion joint extendable between the length for causing the entire link unit to be positioned inside the working chamber and the length for causing the entire link unit to be positioned outside the working chamber.

In a method for referencing a workpiece (2) arranged in a machine tool, an image of the workpiece (2) is first of all created using a camera device (5) of the machine tool and is then displayed on a display device (6). An X-Y display coordinate (9) is selected by a user using the displayed image. A Z reference coordinate is then determined in an automated manner. An X-Y-Z starting coordinate (7) can be calculated on the basis of the Z reference coordinate determined in an automated manner and the X-Y display coordinate (9) input by the user. A measuring probe (8) of the machine tool is then moved in an automated manner to the X-Y-Z starting coordinate (7) and the X-Y-Z reference coordinate of the workpiece (2) is determined on the basis of the position of the measuring probe (8), as predefined by the X-Y-Z starting coordinate (7), by means of a suitable determination method using the measuring probe (8). In order to determine the Z reference coordinate, the measuring probe (8) is moved through the region which can be captured by the camera device (5) along a viewing beam (16) starting from the camera device (5) in the direction of a target point (26) until the measuring probe (8) touches the workpiece (2).

A processing apparatus includes a chuck table having a holding surface for holding a workpiece; a horizontal moving mechanism that moves the chuck table in a horizontal direction and is supplied with a first oil; and a vertical moving mechanism that moves a processing unit in a vertical direction and is supplied with a second oil. Before mounting the workpiece on the holding surface, the holding surface is imaged by a camera while being irradiated with light, and it is examined whether or not the picked-up image is emitting light. If there is a light-emitting part in the picked-up image, it is determined that oil is adhered to the light-emitting part.
