A glass article (100) includes a core layer (102) formed from a core glass composition with a core coefficient of thermal expansion (CTE) and first (104) and second (106) cladding layers fused to first and second major surfaces of the core layer (102) and formed from a clad glass composition comprising a clad CTE. An aperture (120) extends through each of the core layer (102), the first cladding layer (104), and the second cladding layer (106). The clad CTE is less than the core CTE such that each of the first (104) and second (106) cladding layers is under a compressive stress and the core layer (102) is under a tensile stress. A flexural strength of the glass article (100) can be at least about 75 MPa. A peak load sustainable by the glass article (100) in a modified ring-on-ring test can be at most 96.5% less than a peak load sustainable by a reference glass article in the modified ring-on-ring test.

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.

An operational monitoring system for use with a liquid jet cutting system can include an accelerometer coupled to a cutting head of the liquid jet cutting system. The accelerometer can be configured to generate motion data associated with movement of the cutting head. The system can include a computing device operably connected to the accelerometer and having a memory and a processor. The memory can store a planned data set including expected parameters associated with movement of the cutting head along a planned cut path. In some embodiments, the computing device is configured to receive the motion data from the accelerometer and correlate the motion data to the planned data set.

Aspects of on demand apparel manufacturing are described. A system of on demand apparel manufacturing includes a textile cutter and a computing device. The computing device is configured to perform a process including capturing an image of a textile sheet on the textile cutter, where the textile sheet includes a panel for a product. The process further includes identifying cut control factors using the image of the textile sheet, to account for a textile thread, weave, nap, or knit pattern of the textile sheet, a textile print pattern alignment on the textile sheet, or panel deformation of the textile sheet on the textile cutter. The process also includes generating cut control instructions to cut the textile sheet based in part on the image and the cut control factors, and instructing the textile cutter to cut the panel out from the textile sheet based in part on the cut control instructions.

A magnetic cutting platform for use with a (e.g., portable hand operated) die cutting machine that is capable of generating a cutting force to be applied to the cutting platform so that designs can be accurately cut from a sheet material. The magnetic cutting platform includes a (e.g., steel) cutting die having a downwardly facing cutting edge which is aligned with the design of the sheet material. A magnetic base of the cutting platform holds the cutting die in place on the sheet material and prevents the cutting edge of the die from moving out of alignment with the design. The cutting die and sheet material are sandwiched and compressed between upper and lower cutting pads to push the cutting edge of the cutting die downwardly through the sheet material to cut the design therefrom.

A glass article (100) includes a core layer (102) formed from a core glass composition with a core coefficient of thermal expansion (CTE) and first (104) and second (106) cladding layers fused to first and second major surfaces of the core layer (102) and formed from a clad glass composition comprising a clad CTE.

According to various examples, an assembly can include a backing. The assembly can also include a polymeric surfacing film adhered to the backing, the polymeric surfacing film. The polymeric surfacing film can include a first geometric shape. The polymeric surfacing film includes a continuous first cut defining the geometric shape and a continuous second cut spaced apart from and substantially congruent with the continuous first cut in at least one of an x and y direction. A portion of the polymeric surfacing film, located between the first cut and the second cut, is removable from the backing. According to some examples, the assembly can provide certain benefits over state of the art assemblies. For example, according to some examples, providing the first and second cut can make removal of at least the first geometric shape to be quicker and easier, which can result in significant savings in time and wasted materials.

The invention relates to a system made of an electronic display device having a display screen for displaying augmented reality, an electronic memory, and a cutting device for cutting planar cutting stock, e.g., paperboard, corrugated cardboard, film, textile, plastic, foam, or wooden slabs or sheets. The system has a computer unit for computing a position and alignment of the display device in relation to the cutting device. The display device is designed to be worn by a user and positioned in the field of vision of the user. The system is designed to display to the user retrieved cutting-stock-related information by means of the display screen in a manner readable by the user in the field of vision of the user, adapted to the position and alignment of the display device in relation to the cutting device, and linked to an actual and/or setpoint position of the cutting stock.

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 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.
