The technical solution of the present invention is further described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1, a production process of a large non-standard landscape die workpiece comprises the following steps:
step one, calculating a blank material: and calculating the corresponding blank size according to the three-dimensional digital model partition area, and calculating the length, width, high space size and additional allowance of each partition area to obtain the final blank material size in each partition area. Namely, the three-dimensional digital model built by the blank is simulated by adopting any one or combination of more of Rhino, Maya and Magics. The spatial dimensions of each patch are reserved for the necessary additional margin, for example by a 50mm increase in the base dimension.
The whole large non-standard landscape mold is divided into areas, the areas can be areas with the same size or areas with different sizes, and the large non-standard landscape mold can be formed after assembly and combination whether the areas are consistent or not. To facilitate later assembly, the blanks in each panel are numbered and oriented.
Before the first step, the method also comprises a precondition step of simulating simulation: a real object is simulated through software, the defects of a model blank are searched, the production period is shortened, and unnecessary reworking can be avoided. The simulation is carried out by using either one or two of Robotmaster and kukaCNC. The general format src of the post-processing file of the robot is not suitable for processing codes of large figures and expressions due to the fact that the format src is limited by the size of capacity, and the post-processing code format kukaCNC with large capacity is customized to be suitable for processing large nonstandard landscape molds.
Step two, workpiece positioning: and after the blank materials in each area are spliced, fixing the blank materials to a working platform, and writing the blank materials into a coordinate system by using a robot laser positioning space coordinate. The splicing in this step is the splicing of the base material, for example, the size of the foam in each area needs to be spliced to the required size to start processing.
Step three, hot wire cutting and roughing: and calculating a hot wire cutting stroke track according to the space coordinates of the workpiece and the three-dimensional digital model, and performing rough machining on each sheet area. The hot wire cutting speed of the blank in the sheet area is 0.6m/min, and the idle stroke is 2.4 m/min.
The conventional numerical control machining steps are divided into rough cutting and fine trimming, wherein the rough cutting takes a relatively long time. The rough cutting step is replaced by the numerical control hot wire cutter of the custom robot, rough cutting can be quickly started according to the digital-analog outline to enter a fine trimming link, and the machining efficiency is greatly improved. The hot wire cutting control adopts mastercam and ROBIM software to carry out automatic control.
Step four, processing the defective materials: and (4) according to the residual area blank after the rough cutting is carried out by the hot wire cutting, calculating a residual material processing track, generating a kuka CNC code, and carrying out high-speed semi-finishing on the residual material of each area. And (3) carrying out high-speed semi-precision machining on the blank in the wafer area, and adopting a phi 20mm alloy milling cutter, wherein the rotating speed is 3000/min and the feeding speed is 12m/min during working.
Step five, fine modification: and calculating the overall finishing machining track of the residual blank after the residual material machining by using a three-dimensional digital model, generating a kuka CNC code, and performing high-speed finishing machining on the residual material of each block. And (3) carrying out high-speed finishing on the blank in the sheet area, wherein a phi 6mm alloy milling cutter is adopted, and the rotating speed and the feeding speed are 5000/min and 6m/min in the working process.
Step six, product assembly: and combining and splicing each plate area by adopting a building block building mode according to the three-dimensional digital model, and repairing polishing flaws. The splicing in the step belongs to the overall splicing of all the areas after the carving is finished, and a final prototype, namely the large nonstandard landscape die, is obtained. Because the accurate segmentation and the marking positioning are adopted in the digital-analog segmentation stage, the final product combination is completed in the final splicing forming stage according to the building block building mode, the error of manual splicing is avoided, and the accurate and quick splicing is realized.
The method comprises the steps of dividing a blank into large non-standard landscape die subareas through a three-dimensional digital model, respectively processing the blank of each subarea, assembling blank materials in each subarea, saving materials, cutting rough parts by adopting hot wires to improve the processing efficiency, obtaining each complete subarea through rough processing, semi-finish processing and finish processing, and finally combining the subareas into the large non-standard landscape die.
