Embodiment 1

[0056] Scan graphics, orientation marks and other special marks on the first 2D drawing. Determine the direction mark of the 2D drawing, including radial mark, transverse mark and coordinate mark. Establish a three-dimensional space coordinate system according to the direction mark. Divide the graphics of a 2D drawing into several primitives. Use coordinates or functional equations to record the spatial area, shape and specific location of each primitive. Store the data information of each primitive in the primitive database. The database also includes a primitive database for classifying and storing primitives according to primitive types and coordinate areas.

[0057] Read graphics, orientation marks and other special marks on the second 2D drawing. If the second drawing belongs to the same plane as the first drawing, and the graphics are drawn in the same scale, use the coordinates or function equations of the same three-dimensional coordinate system to record the spati...

Embodiment 2

[0087] This embodiment also provides a device for parametrically processing objects based on multi-dimensional drawings, including a graphic input unit, a database unit, a coordinate conversion unit, a calibration unit, a storage unit, and a PLC-controlled processing unit. The graphic input unit reads graphic data of at least one two-dimensional drawing in the form of a graphic element. The database unit stores at least one model based on primitives and associated coordinates. The calibration unit calibrates the characteristic parameters of the model to be processed obtained by matching the input model parameters with the model. The storage unit stores the parameters of the model to be processed and enables the PLC to control the processing unit to process the object to be processed according to the parameters.

[0088] According to a preferred embodiment, the device further includes a coordinate transformation unit. The coordinate conversion unit establishes a three-dimensi...

Abstract

The invention discloses a processing die generation unit. The processing model generation unit includes a first acquisition unit, a second acquisition unit, a third acquisition unit and a first creation unit. The first acquisition unit combines at least one primitive into at least one first processing model based on a coordinate system; the second acquisition unit acquires model parameters input from the outside; the third acquisition unit obtains model parameters to be processed; the second acquisition unit and the third acquisition unit separately store the model parameters input from the outside and the model parameters to be processed in a mode of mapping; the first creating unit creates a second processing model based on a model to be processed and at least one model parameter; and the second processing model is stored to a database unit. The processing die generation unit of the present invention calibrates the obtained processing model so that characteristic parameters of the processing model are more accurate and a processing object which is exactly the same as a drawing can be obtained.

Description

technical field [0001] The invention relates to the field of parametric processing, and in particular designs a processing mold generation unit used in a device for parametric processing objects based on multi-dimensional drawings. Background technique [0002] In the field of mechanical processing, the CNC machine tool system processes according to the two-dimensional graphics input by the user. In this way, the user's input requirements are virtually high. For plane graphics processing, the user may be able to give a more ideal graphics. For more complex three-dimensional graphic processing, if the required processing is an ellipsoid, the graphic input by the user may not be what the user really wants. This will inevitably cause errors between the graphics input by the user and the corresponding processed graphics, and also increase the difficulty of user input. [0003] Chinese patent (CN 104698980 A) discloses a feature-based numerical control vertical lathe parameter...
