Tool deflection compensation with an adaptronic milling spindle
The adaptronic spindle for milling machines can be positioned by piezoelectric actuators in three axial directions. This enables an automatic online-compensation of tool deflections in the milling process. The tool deflection is calculated by the process forces and the tool stiffness previously measured. A new spindle position is calculated to counteract the tool deflection. This procedure can ...
متن کاملClosed Loop Control of Milling Tool Deflection
BACKGROUND Injection molding is an important manufacturing process for optical and mechanical components. The hard steel dies used in injection molding play a direct role in the quality of molded parts. Traditionally, fabricating the dies involved rough milling followed by heat treatment, grinding and polishing. Recently, high-speed machining of heattreated steel (hardness > 55 Rc) has become a...
متن کاملOptimization of Spindle loading and Tool Wear for CNC Turning Machine by Using Intelligent System
Intelligent knowledge based system (IKBS) is developed for optimizing dry CNC turning process using Taguchi method, CNC Machine, EN19 steel as the work piece material, andCutting Insert. Tool wear and spindle loading which are the machining parameters, spindle speed, feed rate, and depth of cut, areoptimized through the intelligent knowledge based system (IKBS). The experimental CNC turning mac...
متن کاملA miniature milling spindle with Active Magnetic Bearings
This paper describes the design and realization of a miniature milling spindle with Active Magnetic Bearings (AMBs). Permanent magnet biased, reluctance type actuators position the rotor in five Degrees of Freedom (DOF), leaving the rotation unconstrained. A rotordynamic model was developed to expedite the controller design, and enabled modeling of the spindle’s performance under the influence ...
متن کاملTool Run-Out Measurement in Micro Milling
The interest in micro manufacturing processes is increasing because of the need for components characterized by small dimensions and micro features. As a result, researchers are studying the limitations and advantages of these processes. This paper deals with tool run-out measurement in micro milling. Among the effects of the scale reduction from macro to micro, tool run-out plays an important ...
