为了修复使用STL文件时产生的一些错误，首先根据错误的特点进行分类，以边的检查作为STL文件错误检查的基础，通过建立错误面片、边和顶点数组来实现错误记录，采用错误描述图来构造错误元素的拓扑关系。考虑到不同错误的特点,建立了合并顶点→空洞修复→裂缝修复→删除多余→重叠修复→错误刷新的基本修复步骤。开发了专用的STL文件修复工具，并通过实例验证了该算法。

Cooling system design in the TV panel pressing operation is of great importance because it significantly affects productivity and the quality of the final part. It would thus be very helpful for mold designers to be able to use a computer aided design tool in determining locations and dimensions of cooling system and process conditions to achieve rapid, uniform and even cooling. For this, a computer simulation has been developed for three-dimensional mold heat transfer of the TV panel pressing process. In the simulation, mold heat transfer is considered as cyclic-steady, three-dimensional conduction; heat transfer within the glass melt region is treated as transient, one-dimensional conduction; heat exchange between the cooling system surface and coolant is treated as steady, as is heat exchange with the ambient air and mold exterior surface. Numerical implementation includes the application of a hybrid scheme consisting of a three-dimensional, boundary element method for the mold region and a finite-difference method with a variable mesh for the melt region. These two analyses are iteratively coupled so as to match the temperature and heat flux at the mold–melt interface. As compared with the experimental data, the numerical simulation developed here is c omputationally efficient and sufficiently accurate.

This residual stress accumulated during the postfilling and cooling stages will lead to warpage of parts after demolding. Based on the principle of viscoelastic mechanics, the linear isothermo-viscoelastic constitutive equation is established. Then this constitutive equation is deduced according to the analysis of the thermorheologically simple material for given boundary conditions of the temperature field. Considering the restraint conditions of mould and the characteristics of injection moulding at the post-filling stage, some reasonable hypotheses have been assumed and hence the stress model is constructed. This mathematical model is solved using the finite difference method. The results can help predict the warpage of plastic products.
