The present disclosure is directed to performing work on a working surface based on a desired path using a working member. The disclosed system advances the working member with respect to the desired path using a first positioning system and a second positioning system. The first positioning system comprises a frame and actuators operable to advance the working member with respect to a portion of the desired path within an adjustment region. The second positioning system comprises actuators operable to move the frame. By moving the frame using the second positioning system, the first positioning system advances the working member with respect to a portion of the desired path that was outside the adjustment region before the frame was moved.

A method for placing pieces intended to be cut automatically from a fabric having a pattern that repeats at a predetermined pitch, called pattern pitch, involves the steps of determining a list of pieces to be placed on the fabric, for at least one piece of the placement, calculating a contour to be placed around the piece, the contour having a variable margin in order to avoid an overlap between adjacent pieces, the margin being a function of a predefined rate of variation of the fabric and of at least one predetermined constraint of placement of the piece on the fabric, and developing a theoretical placement of the pieces on the fabric taking into account the contour to be placed of each piece.

A machining data generation apparatus 4 is used in a sheet process system, which executes a plurality of times of processes by using one or more sheet process apparatuses processing a sheet by performing one or more times of machining and obtains a product in a desired form from the sheet, and generates machining data for operating the sheet process apparatus, and the machining data generation apparatus 4 includes a machining condition input unit 51 that inputs a machining condition for obtaining the product in a desired form from the sheet; a data generation unit 8 that generates the machining data including each machining data piece for operating the sheet process apparatus in order to execute each process in the plurality of times of processes, on the basis of the input machining condition; and a data output unit 71 that outputs the generated machining data to the sheet process apparatus that executes each process.

Planner insight analytics identifies orders and sizes customers can execute to achieve business and operational efficiency. Generating optimal trimming patterns for trimming raw rolls and/or sheets of a flat sheet stock/customer orders includes: (a) receiving customer orders, primary and secondary machine specifications, warehouse inventory, and trade constraints; and (b) generating solutions for (i) order quantity fulfillment, (ii) a primary cutting pattern for the primary machine, (iii) a secondary cutting pattern for the secondary machine, and (iv) inventory details, wherein the solutions are generated with consideration of the initial trade constraints; (c) executing a batch and generating suggestions; (d) generating modified solutions for the parameters in step (b) using revised trade constraints derived from the suggestions generated that override the initial trade constraints in (c); and (e) operating a cutting apparatus. Trim optimization knapsack algorithm with objective function with term relating to trim loss which is eventually minimized is employed.

A method generates a nesting plan for controlling a cutting process of a flatbed machine tool for cutting workpieces from a material sheet. The nesting plan includes an overlap-free arrangement of sub-spaces corresponding to the workpieces in a two-dimensional planning space as well as a spatial arrangement of predetermined supported spaces. After each new insertion of a sub-space during nesting, a packing density evaluation and at least one evaluation incorporating the position data of the respective initial position of the newly inserted sub-space in a local search space are performed.
