| Laser cutting has various applications in different manufacturing industries,with its advantages,it is particularly suitable for enterprises to develop new products or improve existing products,after the model is built,it can be laser cutting to get the product.Usually there will have a lot of repetitive operations during the design period and data interaction problems during the initial production period,and these are not good for companies.This paper is based on engineering practice,and use Solid Works to design the pipe,and realize the parametric rapid modeling program by using the IGES standard to achieve data transmission between different systems.The main contents are summarized as follows:First of all,analyze the three modeling methods of Solid Works,as well as its secondary development technology.According to the features of round and square pipes commonly used in enterprises,this paper design the user interface by using the given API interface,and also realize the rapid parametric modeling of pipes.Not only saves many repetitive design steps,but also retains flexibility for the company’s extra designs,and finally through the establishment of a round pipe instance to verify the correctness of the program.Secondly,in order to solve the problem of data interaction between the user and the enterprise CAD / CAM system,use IGES files as an intermediary for data interaction,and analyze the internal structure of IGES files,especially rational B-spline curve entity and trimmed surface entity.Realize the extraction of information on the processing surface to design a program to facilitate subsequent analysis,and design the processing path according to their characteristics.Then,using the MFC framework to design a preprocessing page for reading files,and display the machining contour.Finally,by using the previous model,successfully showing the contour of the generation processing and the corresponding processing path,verifying the correctness of the program. |
