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.
根据之前的研究和第一个资助期的结果,由于这些系统所基于的夹紧方法存在各种缺点,因此不可能普遍使用众所周知的微夹紧系统。例如,尽管机械夹紧具有夹紧时间短、夹紧刚度高、自动化能力强、资金和操作成本低的特点,但由于存在损坏的风险,无论是软件还是薄壁件都无法固定。蜡夹可以实现非常高的保持力,并可靠地夹紧各种微型工件,而不会损坏它们。然而,由于工件的热膨胀和浮动,这种方法几乎不可能在没有特殊定位系统的情况下确保足够的夹紧精度。此外,与机械夹紧相比,蜡夹紧时间更长。所有这些都导致了额外的时间和成本,并且使得这种方法只能有效地用于小批量。因此,需要一种普遍可用的微夹紧系统。该项目的目标是开发和研究新的,普遍可用的混合微夹紧系统,一方面,实际使用在第一个资助期间获得的关于已知夹紧装置的特性和适用性的知识,另一方面,获得未知或未研究的混合微夹紧装置的行为和特性的新的基本知识。新型的混合微夹紧系统将通过各种众所周知的基于材料、力或形式封闭的夹紧方法的组合来开发,包括冰、蜡、胶、真空、卡盘夹爪等夹紧。这种传统方法的组合应该导致同时使用它们不同的优点,例如可靠和无损伤的工件夹紧和高精度和可重复性的固定,和/或补偿它们的缺点,例如夹紧刚度的增加。然而,这必须通过这些混合微夹紧系统的特性的理论和实验研究来验证。将在这些研究期间获得的基本知识将纳入第一个供资期间建立的数据库系统。
