The swivel knife holder assembly includes a shoulder screw defining an axis, and having a proximal threaded end and a distal head, and mounted on the shoulder screw is a bobbin assembly. The swivel knife holder assembly also includes a shell defining an interior, and having a distal opening and a proximal opening. A core is secured in the interior and is coupled to a knife for cutting fabric material. The proximal opening of the shell is defined by a flange and houses the shoulder screw therein. Threadably coupled to the proximal threaded end of the shoulder screw is a stem. The stem secures the bobbin assembly within the shell and also includes a mounting surface for engaging a reciprocating drive mechanism.

Methods, apparatus, and systems for cutting material used in fused deposition modeling systems are provided, which comprise a ribbon including one or more perforations. Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.

A cutting device controls a movement mechanism based on cutting data for cutting, along a cutting line, an object to be cut placed on a placement member. The cutting device acquires an attribute of the cutting line. The cutting device decides, based on the acquired attribute, a correction amount to correct the cutting line. The cutting device generates, based on the cutting data, corrected cutting data for cutting the object to be cut along the cutting line corrected by the decided correction amount. The cutting device controls the movement mechanism based on the generated corrected cutting data and cutting the object to be cut.

A computerized mat cutter machine system includes a mat table having a cutter surface, at least one clamp moveable between a clamped position to secure a matboard to the mat table and a non-clamped position, a cutter head for performing at least one of cutting and finishing a design in the matboard, and a clamp controller bus for communicatively coupling a board controller to a clamp controller of the at least one clamp. The clamp controller bus includes a first bus configured as a dual ended serial differential bus that allows signals to flow from the board controller to the clamp controller, and a second bus configured as an analog bus that allows signals to flow from the clamp controller to the board controller.

A knife assembly for cutting a substrate during relative motion between the knife and the substrate, the assembly including a knife having a distal knife blade and a proximal knife shaft attached to a holder rotatable about a first axis perpendicular to the substrate to define a cut direction angle. The holder is also configured to rotate the knife blade about a second axis perpendicular to the first axis to form a notch angle relative to the first axis. The notch angle is preferably automatically infinitely adjustable within a range of angles. The holder may also, optionally, be configured to rotate the knife blade about a third axis perpendicular to a plane defined by the knife blade to adjust an angle of attack of the knife blade relative to the substrate.

A sheet processing system conveys a material sheet in a first direction; calculates an inclination angle of the first registration mark of the material sheet with respect to the first direction; and includes cutting blades configured to cut the material sheet to produce sheet pieces and a cutting direction adjustment mechanism configured to adjust a cutting direction to a direction of the inclination angle. The sheet processing system conveys the sheet piece in a second direction; and includes a guide member configured to extend in the second direction and to guide a cutting end of the sheet piece, a processing place position identification section configured to identify a position on a conveyance path of a processing place of the sheet piece based on the inclination angle, and processing mechanisms configured to perform processing on the processing place whose the position on a conveyance path is identified.

A dicing device includes: a workpiece table; a cutting unit including a blade and a spindle; an XY-direction drive unit; a Z-direction drive unit; a first measuring instrument for measuring a Z-direction position of a surface of a workpiece held on a holding surface of the workpiece table; a second measuring instrument for measuring a Z-direction displacement of the holding surface; a correction amount calculation unit for calculating a correction amount for the Z-direction position of the cutting unit based on a table displacement map showing the Z-direction displacement at each position on the holding surface, the Z-direction displacement having been measured in advance by the second measuring instrument and based on the Z-direction position of the surface of the workpiece, measured by the first measuring instrument; and a control unit for controlling, when the workpiece is cut by a blade, the Z-direction drive unit based on the correction amount.

A processing system (10) and corresponding method (158) are provided for processing workpieces (WP), including food items, to cut and remove undesirable components from the food items and/or portion the food items while being conveyed on a conveyor system (12). An X-ray scanning station (14) is located on an upstream conveyor section (20) to ascertain size and/or shape parameters of the food items as well as the location of any undesirable components of the food items, such as bones, fat or cartilage. Thereafter the food items are transferred to a downstream conveyor (20) at which is located an optical scanner (102) to ascertain the size and/or shape parameters of the food items. The results of the X-ray and optical scanning are transmitted to a processor (18) to confirm that the food item scanned by the optical scanner is the same as that previously scanned by the X-ray scanner. Once this identity is confirmed, if required, the data from the X-ray scanner is translated or transformed onto the data from the optical scanner. Such translation may include one or more of the shifting of the food items in the X and/or Y direction, rotation of the food item, scaling of the size of the food item, and sheer distortion of the food item. Next, the location of the undesirable material within the food item is mapped from the X-ray scanning data onto the optical scanning data. Thereafter, the undesirable material is removed by a cutter(s) (28). The food item may also (or alternatively) been portioned by the cutter(s) (28).

Embodiments of the present disclosure are drawn to additive manufacturing apparatus and methods. An exemplary additive manufacturing method may include forming a part using additive manufacturing. The method may also include bringing the part to a first temperature, measuring the part along at least three axes at the first temperature, bringing the part to a second temperature, different than the first temperature, and measuring the part along the at least three axes at the second temperature. The method may further include comparing the size of the part at the first and second temperatures to calculate a coefficient of thermal expansion, generating a tool path that compensates for the coefficient of thermal expansion, bringing the part to the first temperature, and trimming the part while the part is at the first temperature using the tool path.

A positioning jig includes a holding portion, a contact portion, and an operating portion. The holding portion holds the cartridge. A portion of the contact portion contacts a writing portion of the pen when the cartridge is held in the holding portion and the pen is held in the accommodating portion. The contact portion is able to rotate with a direction in which an axis of the pen extends as a first rotational axis. The operating portion performs an operation to rotate the contact portion. The contact portion restricts rotation of the pen about the first rotational axis with respect to the contact portion by contacting the writing portion of the pen and positions the pen in a rotational direction about the first rotational axis with respect to the cartridge.
