Experimental Study of the Effect of Conformability on Static Stability in a Flexible Machining Fixture
نویسندگان
چکیده
An experimental study of the effect of fixtureworkpiece conformability on system static stability is presented. Conformability is defined as the geometric similarity between the workpiece and the smallest polyhedron fit over all fixture-workpiece contacts. Two metrics, C1 and C2, are introduced to quantify global and local conformability, respectively. The elastic displacement of the workpiece with respect to the fixture is used as the experimental stability metric. Experiments are carried out with a pin-array type flexible machining fixture. It is found that static stability decreases with decreasing fixture-workpiece conformability.

متن کاملThe Effect of Core Stability Exercises on Static and Dynamic Balance in Healthy Older Men
Abstract Introduction: Disturbance in maintaining balance and controlling posture is one of the consequences of aging, which, with changes in standing and walking patterns, causes a decrease in functional readiness in the elderly, which leads to a decrease in the sense of balance, loss of coordination, and muscle weakness in these people. As a result, it causes many problems such as frequent f...
متن کاملUsing Error Equivalence Concept to Automatically Adjust Discrete Manufacturing Processes for Dimensional Variation Control
Traditional statistical process control (SPC) has been widely employed for the process monitoring in discrete part manufacturing. However, SPC does not consider any adjustment preventing the process drift. Furthermore, many in-line adjustment approaches, such as thermal error compensation and avoidance, are designed only for machine tool error reduction. This paper intends to fully utilize the ...

متن کاملThe Analysis of Experimental Process of Production, Stabilizing and Measurement of the Thermal Conductivity Coefficient of Water/Graphene Oxide as a Cooling Nanofluid in Machining
The abrasion is a significant issue, especially in machining of rigid steels. A functional and suitable approach for enhancing the heat transfer from machining area is using an intermediate fluid with higher heat transfer potential instead of common fluids. The objective of this experimental study is to discuss production, stability and thermal conductivity examination of water/graphene oxide n...
