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 cutting device includes a platen, a mounting portion, a first movement mechanism, a second movement mechanism, a detector, a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring cutting data, acquiring a contact position output by the detector when the cutting blade comes into contact with the holding member, and controlling the first movement mechanism in accordance with the cutting data to move the mounting portion and the holding member to a cutting start position. The processes include controlling the second movement mechanism, at the cutting start position, to move the mounting portion in the third direction to a cutting position set on the basis of the contact position, and controlling the first movement mechanism in accordance with the acquired cutting data to perform cutting processing.

A cutting device comprises an upper support and a lower support arranged above and below a media plane, and a contact-free coupling device to engage and disengage the upper support and the lower support, wherein one of the upper support and the lower support is a master support and the other one of the upper and lower supports is a slave support, and further comprises a master cutting blade arranged in the master support, wherein when the upper and lower supports are engaged, the slave support follows movement of the master support.

A sheet processing apparatus includes a sheet conveyor, a plurality of processing tools, and a tool moving device. The sheet conveyor is configured to convey a sheet. The plurality of processing tools is disposed in a conveyance direction of the sheet and is configured to perform processing to the sheet. The tool moving device is configured to move the plurality of processing tools in an intersecting direction intersecting the conveyance direction of the sheet.

A cutting device includes: a movable blade; a moving mechanism moving the movable blade and having a first mechanism portion movable between a first operating position and a first non-operating position and a second mechanism portion movable between a second operating position and a second non-operating position; a first detecting portion and a second detecting portion detecting positions of the first mechanism portion and the second mechanism portion; and a controller configured to perform: setting, when one of the first detecting portion and the second detecting portion detects abnormally, updated positions of the first operating position and the second operating position or the first non-operating position and the second non-operating position. The updated positions are set based on detection result of another of the first detecting portion and the second detecting portion and are new start points of movement of the first mechanism portion and the second mechanism portion.

A cutting machine comprising one or more form tubes that are divided in two in the longitudinal direction into a front form tube section and a rear form tube sectionat least across a portion of its circumference, so that the two form sections can be moved from a pressing position in which they are aligned with each other into a loading position in which they are not aligned with each other, and in the loading position the rear form tube section can be loaded with a new meat strand while the rest of the previous meat strand is still being cut into slices and moved in the front form tube section. The blade may be disposed to simultaneously cut slices from a plurality of form tubes and may be disposed for motion in the longitudinal direction as well as a direction transverse to the longitudinal direction.
