摘要:
A series of input units (a machining attribute specification unit, a geometric element selection unit, and an additional information input unit) of a CAD/CAM apparatus according to the present invention enables machining attributes to be input in an interactive manner while such data are displayed on a display, simplifying input procedures of various items of machining attribute information, and enables the input various item information to be displayed on the display, making confirmation of the input information easy by virtue of the simplified inputting and by the visual confirmation.

Automatic programming apparatus includes: a material shape data input unit that receives input of data of material shape; a processing program storage unit that stores therein data of material shape and processed unit data; a processed unit data input part that receives an input of other-processed-unit-reference-type processed unit data referencing processed region shape data contained in the processed unit data; a processed region shape generating unit that generates processed region shape data in the processed unit data for partial processing, based on data of material shape and processed region shape data referenced by other-processed-unit-reference-type processed unit data; and a control command generating unit that generates control command data, based on processed unit data for partial processing containing processed region shape data.
摘要:
Shape data relative to a hemmed edge in view of production technique requirements is added to shape data relative to a design surface using a CAD system. Curvatures of curved lines, curvatures of curved surfaces, offsets and distances between shape surfaces, and angles between shape surfaces of the shape data are analyzed and verified.

A method of generating embroidery data for controlling stitching out by an embroidery machine. The method comprises simulating a position of a needle on an embroidery workspace and updating the needle position in response to an input control signal. A series of stitch time points is generated and embroidery data defining a stitch is generated. The data defining a stitch being dependent upon the needle position at a corresponding stitch time point and at a preceding stitch time point.

A CAD/CAM apparatus is adapted such that each set of machining process information representative of machining attributes and the relative machining path and the order of machining are stored in a storage portion associated with each geometric element of each shape of an object, and the machining process information can be modified according to the need and stored again by a machining process edition portion, whereby it is made possible to input information relative to specifications of machining methods in an interactive manner with the display screen. The apparatus is further adapted such that NC data for machining a geometric shape are generated based on the information stored in its storage portion, whereby, differing from prior art apparatuses, it is enabled, even when there are mixed particular specifications of machining conditions for individual part of a geometric shape of the object and a common specification of machining conditions for a unit of geometric shape of the object, to output the NC data for all the shapes in a lump. Further, it is adapted such that any desired portion of the sets of machining process information stored in the storage portion associated with geometric elements can be selectively modified in the machining process edition portion so that new NC data based on the modified machining process information are provided, thereby eliminating the need for re-defining geometric shapes over again in contrast with the prior art apparatuses and enabling the NC data incorporating the modified machining process information to be formed easily and quickly.

摘要:
A contour configuration machining system of an interactive numerical control apparatus is provided for carrying out a machining operation by a lathe by programming a predetermined contour configuration based on configuration data of straight lines, arcs and the like. A cutting direction (9) is independently set on a display (1) for each of the above configuration data and the machining operation is carried out by moving a tool according to the set cutting direction, whereby the machining efficiency is improved when a configuration composed of a series of contours is to be machined.
