摘要： A machine has a tool head which rotates on a C-axis (about the Z-axis) and an A-axis (about the X-axis). A tool length vector is multiplied by a matrix whereby a misalignment component δs-H and the incline error (αs-H, βs-H, γs-H) of a spindle are corrected so that the tool length vector due to the misalignment of the spindle is obtained. The vector thus obtained is further multiplied by a transformation matrix that includes a rotation instruction α for the A-axis and misalignments of the A-axis εa-H (αa-H, βa-H, γa-H) to correct the misalignment of the A-axis so that the tool length vector as found when the A-axis has rotated by an equivalent of instruction α is determined. The vector thus determined is further multiplied by a transformation matrix that includes a rotation instruction c for the C-axis and misalignments of the C-axis δac-H (αc-H, βc-H, γc-H) to correct the misalignment of the C-axis, so that a tool length vector as found when the C-axis has rotated by an equivalent of instruction c is determined. The tool length vector thus determined is added to the vector of positional instruction values (x, y, z) and a workpiece origin offset vector Mwo-H, so that the machine position Vm-H′ is obtained.

摘要： A stereoscopic modeling apparatus is provided. The stereoscopic modeling apparatus includes a modeling tank, a liquid discharger, and a powder supplier. In the modeling tank, a powder layer including a powder is formed and a modeling layer in which the powder in the powder layer is bonded into a required shape is laminated. The liquid discharger discharges a modeling liquid to the powder in the modeling tank. The powder supplier supplies the powder to the modeling tank. The powder supplier supplies the powder to the powder layer while at least a part of the modeling liquid discharged from the liquid discharger and adhered to a surface of the powder layer remains existing on an outermost surface of the powder layer.

摘要： A numerical controller controls a three-axis machine tool that machines a workpiece, mounted on a table, with at least three linear axes. The numerical controller includes a workpiece mounting error compensation unit that compensates a mounting error caused when the workpiece is mounted. The workpiece mounting error compensation unit performs an error compensation with respect to an instructed linear-axis position with amounting error which is set beforehand, in order to keep a position with respect to the workpiece at a tool center point position, based on the instructed linear-axis position of the three linear axes to obtain a compensated linear-axis position. The three linear axes are driven based on the obtained compensated linear-axis position.
