项目摘要

According to the results of the previous studies and the 1st funding period, a universal usage of the well-known micro clamping systems is not possible due to various disadvantages of the clamping methods, on which these systems are based. For example, though the mechanical clamping, which shows a very short clamping time, high clamping stiffness and automation capability, as well as low capital and operating costs, nether soft nor thin-walled workpieces can be fixed because of the risk of their damage. The wax clamping allows to achieve very high holding forces and to clamp various micro workpieces reliably and without their damage. However, it is hardly possible with this method to ensure a clamping accuracy sufficient for micromachining without special positioning systems due to the thermal expansion and floating of the workpiece. In addition, the clamping with wax shows much longer clamping times than the mechanical clamping does. All this results in an additional time and costs and makes an efficient usage of this method only for small batches possible. Hence, there is a need for a universally usable micro clamping system.The goal of this project is the development and study of new, universally usable, hybrid micro clamping systems, on the one hand, to use practically the knowledge about the properties and suitability of the known clamping devices for micromachining, which were obtained during the 1st funding period and, on the other hand, to obtain new fundamental knowledge of the behavior and properties of unknown or not studied, hybrid micro clamping devices.The novel hybrid micro clamping systems are to be developed through a combination of various, well-known clamping methods based on material, force or form closures, including the clamping with ice, wax, glue, vacuum, chuck jaws etc. This combination of the conventional methods should result in a simultaneous usage of their different advantages, such as a reliable and damage-free workpiece clamping and a fixation with a high accuracy and repeatability, and/or in a compensation of their disadvantages, such as an increase in the clamping stiffness. However, this must be verified through theoretical and experimental studies of the properties of these hybrid micro clamping systems. Fundamental knowledge, which will be obtained during these studies, is to be implemented into the database system created during the 1st funding period.

根据先前研究的结果和第一个资金期，由于这些系统所基于的夹紧方法的各种缺点，因此无法普遍使用众所周知的微型夹紧系统。例如，尽管机械夹具显示出非常短的夹紧时间，高夹紧刚度和自动化能力，以及低资本和运营成本，但由于其损坏的风险，可以固定柔软的或薄壁的工件。蜡夹可以实现很高的固定力，并可以可靠地夹住各种微型工件，而不会损坏它们。但是，这种方法几乎不可能确保由于工件的热膨胀和浮动而在没有特殊定位系统的情况下进行微加工的夹紧精度。此外，用蜡的夹紧显示的时间比机械夹具更长。所有这些都会导致额外的时间和成本，并有效地使用了这种方法，仅对小批量进行了可能。因此，该项目的目的是开发和研究新的，可用的，可用的，混合的微夹具系统，一方面是使用有关已知夹具设备的属性和适用性的知识，并在筹资期间获得了新的知识，并获得了新的知识，并获得了新的知识，并获得了新的知识，并获得了新的知识，并获得了新的筹集资金，并且在其他方面获得了新的知识，并获得了新的知识，并获得了新的知识，并获得了新的知识，并获得了新的知识，并获得了新的知识，并获得了新的知识，并获得了新的知识，并且可以在其他方面获得新的知识。杂化微型夹具。新型杂化微夹具应通过组合基于材料，力或形式封闭的各种知名夹紧方法的组合，包括用冰，蜡，蜡，胶水，真空，chuck嘴，Chuck jaws等夹紧夹具。常规方法的这种可靠的方法和同时的损害，例如同时的损害，例如，这些方法可靠，例如，这些方法可靠，例如，这些方法可以及其同时使用，例如，这些方法是一种可靠的，例如，这些方法是一种可靠的，例如，一定会及其同时的损害，并且是一种可靠的损害，并具有一定的损害，例如，这些方法是一种可靠的，例如，这些方法是一种可靠的，例如，且具有一定的损害，例如，这些方法是一种可靠的，例如，这些方法是一种可靠的，例如，且构成了一个 - 构成的构造，例如，且具有同时的损害。具有高精度和重复性的固定，和/或在其缺点的补偿中，例如夹紧刚度的增加。但是，必须通过理论和实验研究对这些混合微型夹紧系统的性质进行验证。将在这些研究期间获得的基本知识将在第一个资金期间创建的数据库系统中实施。
