【摘要】： 本文针对石材加工及装饰行业的基本特点，在AutoCAD平台上进行了针对性较强的二次开发。所开发的系统解决了石材计算机辅助设计中的一些常见的问题,提高了设计效率，降低了成本。同时，对CAD／CAM技术在石材加工及装饰行业中的应用和普及具有一定的借鉴作用。该系统中，着重分析和开发了石材铺设的参数化分割和编号、石材的艺术拼花、石材加工信息在不同软件中的通信即加工单的开立、以及旋转搂梯扶手石材贴片空间曲线的建模等几个功能模块。其中，石材铺设的参数化分割和编号功能，可以根据所选定的铺设区域，输入石材铺设参数和多种铺设方式，自动完成分割设计并编号，从而选择最佳方案。同时，把加工单中所需的信息加工成具有块引用属性的明细表，然后通过Automation Active自动化技术完成 AutoCAD和 Exce1之间的数据传输，然后在Excel中手工完成加工单的其它部分工作，最后完成加工单的开立。石材的艺术拼花功能，通过建立基本图案库和石材素材库，借助其它专业图形处理软件，可以快捷地完成石材的艺术拼花设计，并可以不断充实和完善基本图库和艺术拼花参考图库。此外，针对旋转楼梯扶手石材贴片施工时所出现的厚度和垂直方向易产生较大错边的问题，提出了一种新的建模方案和加工措施，即在保证测量精度的基础上，，分段以空间螺旋线逼近，经过计算机处理后的参数直接可供数控加工使用，最后把石材贴片加工成螺旋线型的柱面弧形扳。该方法简单易行，数据处理方便，而且精度很高，极大地减少了传统方法所造成的误差，也避免了施工时现场切割、打磨的麻烦，完全可以满足实际需要。
[Abstract]:In view of the basic features of the stone processing and decoration industry, this paper is aimed at the AutoCAD platform.
A relatively strong two development. The developed system solves some of the common stones in the computer aided design of stone.
The problem is to improve the design efficiency and reduce the cost. At the same time, the CAD / CAM technology is processed and installed in stone.
The application and popularization of ornament industry has certain reference function.
In this system, the parameterized segmentation and numbering of stone laying are emphatically analyzed and developed, and the art of stone is the art of stone laying.
Mosaic, stone processing information communication in different software in the processing of a single opening, and a revolving stair handrail
Several functional modules such as the modeling of the space curve of the stone patch. Among them, the parameterized partition and compilation of stone laying
Number function, according to the selected area of laying, input stone laying parameters and a variety of laying methods,
Perform the segmentation design and number, so as to select the best scheme. At the same time, add the information needed in the processing list.
Working into a list with a block reference attribute, then completed by Automation Active automation technology
Data transmission between AutoCAD and Exce1, and then manually completing other parts of the processing list in Excel
Work, finally completed processing. The single open stone art parquet function, through the establishment of basic pattern library
And the stone material library, with other professional graphics software, can quickly complete the stone art parquet
The design, and can continue to enrich and improve the basic library and art gallery. In addition to the reference pattern, rotation
The thickness and vertical direction of the stone patch in the staircase are easily caused by the larger wrong side.
A new modeling scheme and processing measures are proposed, that is, on the basis of ensuring the accuracy of the measurement, the subsection is empty.
With the approximation of the spiral line, the parameters processed by the computer can be directly used for numerical control processing. Finally, the stone material is used.
The patch is machined into a spiral line shaped cylindrical arc wrench. This method is simple and easy to handle and is convenient for data processing.
The degree is very high, which greatly reduces the error caused by the traditional method, and avoids the field cutting during construction.
The trouble of grinding can fully meet the actual needs.
