Abstract Our ability to shape and finish a component by combined methods of fabrication including (but not limited to) subtractive, additive, and/or no theoretical mass-loss/addition during the fabrication is now popularly known as solid freeform fabrication (SFF). Fabrication of a telescope mirror is a typical example where grinding and polishing processes are first applied to shape the mirror, and thereafter, an optical coating is usually applied to enhance its optical performance. The area of nanomanufacturing cannot grow without a deep knowledge of the fundamentals of materials and consequently, the use of computer simulations is now becoming ubiquitous. This article is intended to highlight the most recent advances in the computation benefit specific to the area of precision SFF as these systems are traversing through the journey of digitalization and Industry-4.0. Specifically, this article demonstrates that the application of the latest materials modelling approaches, based on techniques such as molecular dynamics, are enabling breakthroughs in applied precision manufacturing techniques.

先进材料数字化固体自由成型制造中的现代分子动力学模拟视野

摘要 我们通过组合制造方法（包括（但不限于）减法、加法和/或在制造过程中没有理论质量损失/加法）对部件进行成形和精加工的能力现在普遍称为固体自由成型制造 (SFF)。望远镜反射镜的制造是一个典型的例子，首先应用研磨和抛光工艺使反射镜成形，然后通常应用光学涂层以增强其光学性能。如果没有对材料基础知识的深入了解，纳米制造领域就无法发展，因此，计算机模拟的使用现在变得无处不在。本文旨在强调精确 SFF 领域特有的计算优势的最新进展，因为这些系统正在经历数字化和工业 4.0 的旅程。具体而言，本文展示了基于分子动力学等技术的最新材料建模方法的应用正在实现应用精密制造技术的突破。
