A multilayer-type sheet processing apparatus includes processing units. Each of the processing units includes first guide members extending in an X-direction, first moving bodies arranged on the first guide members, second guide members supported to the first moving bodies and extending in a Y-direction, second moving bodies arranged on the second guide members, Y-drive mechanisms configured to drive the second moving bodies along the second guide members, work areas each arranged in a plane including the X- and Y-directions, and tools, which are arranged in the second moving bodies to be able to move close to and separate away from the work areas, and are each configured to form a processing line on a sheet arranged on a work area. The first moving body that is moved by the X-drive mechanism and the first moving bodies of the other units are coupled to each other.

Methods of trimming fiber reinforced polymer composite workpieces are provided which use a pure waterjet discharged from a cutting head in liquid phase unladened with solid particles at an operating pressure of at least 60,000 psi and in combination with other cutting parameters to provide a final component profile without delamination, splintering, fraying or unacceptable fiber pullout or fiber fracture.

A method of partitioning involves a predetermined layout of parts that are to be cut out from a sheet of flexible material by moving at least one cutter tool along two directions in at least two distinct and determined cutting windows along which the material is advanced in succession. Starting from a predetermined layout of the parts in the material, the method comprises: automatically creating mutually distinct groups of parts by allocating each part to a single group of parts as a function of its geometrical position, each group of parts being associated, for cutting out, with a single cutter tool and with a single cutting window; and applying spacings between the various groups of parts.

This disclosure concerns methods for processing and grading food articles including x-raying the food articles a first time and taking a 3D image of the food articles.

A device for the cutting of material on a plane material supporting surface, the device having at least one cutting unit which can be motor-driven in a controlled manner above the material supporting surface in the direction of the X- and Y-axis of a Cartesian coordinate system that is parallel to the material supporting surface, and having an oscillation drive and a cutting knife, wherein the oscillation drive sets the cutting knife into linear oscillations along an oscillation axis that is perpendicular to the advancing direction of the cutting knife. The cutting knife is pivotable around a pivot axis that is parallel to the material supporting surface and is aligned with the rotary axis of a rotary drive shaft of an electric motor of the oscillation drive.

A water jets cutting machine includes a first rotating seat driven by a first motor to rotate about a first rotation axis, a second rotating seat driven by a second motor to rotate about a second axis, a water jets cutting head, an inertial measurement unit (IMU) for detecting an inclination angle of the water jets cutting head, and a controller connecting the first and second motors and the IMU. The controller is able to control the first and second motors to instantaneously conduct compensation for angular deviation of the water jets cutting head according to attitude and position signals which are fed back to the controller by the IMU.

A method is provided for automatically modifying the cutting paths for parts to be cut out from a flexible material by automatically moving a cutter tool along predetermined cutting paths. The cutting paths are associated with each part being defined by a succession of cutting segments forming a polygon. Two cutting segments are identified and belonging to two different parts for cutting out in the material and for which a maximum distance condition between these cutting segments is satisfied. Two cutting segments are verified for being situated facing each other, and that no other cutting segments lie between the two cutting segments. A common cutting path for the two cutting segments is computed, and a common cutting path is connected to the cutting paths of the two parts for cutting out to obtain modified cutting paths for the two parts for cutting out.

A processing apparatus for performing not only cutting and drawing, but also other processing, and a cartridge used for the processing apparatus are provided. The processing apparatus includes a first cartridge including: a first processing tool to form a machining mark by grinding or cutting a surface of a sheet-like object; an actuator to operate by an external power supply and drive the first processing tool; and a first housing to accommodate the first processing tool where a tip of the first processing tool is exposed and accommodate the actuator. The processing apparatus also includes a carriage including a mounting section which the first cartridge is detachably mounted; a transfer mechanism to move the object and the carriage relatively to each other; and a control circuit to control driving of the transfer mechanism to form the machining mark on the surface of the object by the first processing tool.

A candidate point selection processor selects, as candidate points, vertices on an outline. A search point selection processor selects, from the candidate points, a reference search point to be used to search for a point that serves as a cutting line endpoint. A reference line setting processor sets a reference line connecting a reference point with the search point. A candidate line setting processor sets candidate lines connecting the search point with the candidate points other than the search point. A candidate line selection processor selects, as a selected candidate line, the candidate line located only within a non-effective region. An angle calculation processor calculates an angle between the reference line and the selected candidate line. A cutting line setting processor sets a cutting line connecting the search point with the candidate point of the selected candidate line defining an angle with the reference line that is the smallest angle calculated.
