More Information
Summary:The invention provides a cutting device, capable of enable an operator to correctly identify the distortion of sheet materials, so that the operator can cut the sheet materials along the cutting patterns corresponding to the distortion of the sheet materials, as a result, the pattern sheets with less distortion can be obtained. The cutting device (1) has a cutting workbench(2), a stretching device (3), a projection controlling device (4) and a projector(5). A grid (6) is projected on the surface of a cloth (7) arranged on a bearing surface (21) of the cutting workbench (2) by the projector (5). An operator visually identifying the grid (6) operates a controller (41) to adjust the position of the adjusting points (P1 to P9) of the grid (6), so that the grid (6) is deformed along the patterns of the cloth (7). The cutting patterns (75,76) are deformed correspondingly to the deformed grid (6), and the deformed grid is projected on the surface of the cloth (7). The position and angle of the cutting patterns (75,7
