Adaptive Fixturing System for the Smart and Flexible Positioning of Large Volume Workpieces in the Wind-power Sector

Abstract

Quality and productivity in a manufacturing process depend considerably on the toolkits used, whose basic functions are to position the component into a right position relative to the cutting tool and to hold the component tightly to avoid displacements during the machining. In this document the design of a smart and adaptive fixture is presented for the accurate positioning of a planet carrier with very strict requirements of tolerances and for an intelligent adjustment during the machining process when required. This device will allow the manufacturer reducing the manual inspections, automatizing the adjustment tasks and improving the machining process setup time, increasing consequently the productivity and achieving the required accuracy and the required geometrical quality of the part. The development of the intelligent fixturing will be focused mainly in the conception of a high precision actuator capable of moving the large part with the required tolerance. Moreover, a testbench has been developed that will allow validating the actuator, assuring therefore its applicability in the future industrialization of the fixture device.

Yoke Stress Analysis of New Engines by Using Finite Element Analysis

“…With the help of the equipment, producers may produce more components with the needed precision and form quality while reducing the number of manual checks and automating adjustment duties. The construction of very precise actuators capable of moving massive parts to the necessary tolerances is the primary focus of the development of smart xtures (Olaiz et al, 2014).…”

Research on Rapid and Accurate Fixture Design for Non-Intervention Machining of Complex Parts

“…Aerospace equipment plays an important role in industry [1][2][3]. It has the characteristic of poor consistency and is difficult to transfer its machining data and to ensure the wall thickness and the size of butt assembly features [4]. The traditional manufacturing process has some problems due to the complex process flow of the complex cabin, such as the easy occurrence of accumulation errors due to multiple clampings.…”

“…Fixturing costs can account for 10-20 percent of the total cost of a manufacturing system. ese fixturing and tooling costs rise in short batch manufacturing applications because fixturing is typically unique to each workpiece [9]. However, fixture design frequently relies heavily on the experience and knowledge of fixture design engineers, resulting in inconsistency in fixture design quality [2].…”
