The efficiency of the application a new technology for fir-tree slots treatment in turbine discs based on combination pre-slotting operations «house» by hydro-abrasive (HAT) and final broaching herringbone CNC machine comparison with milling, deep grinding EDM-ing methods is viewed. Problems arising within manufacturing operating broaches often cause down-time both types: main tool production. ...

Abstract. A Fuzzy-PID controller is designed for tracing reference cutting forces in grinding by integrating a high performance fuzzy controller and an easy to use PID controller. When the error of the grinding force is large, in order to respond quickly, the fuzzy controller with a self-tuning factor is adopted and the Max-Proc strategy is also used. This will be good for fuzzy reasoning. If t...

Automation of grinding of metalcastings is desirable for many reasons. The major reasons are dangerous working conditions, low productivity, and inconsistency in human operations. As an approach to the automating grinding process, a gantrydriven grinding machine is proposed to manipulate an industrial hand grinder and control the grinding force applied to the work piece. To increase the materia...

Abstract Super abrasive diamond grinding wheels are the most promising tools for precision machining of advanced ceramics and carbide materials. However, efficiency conventional conditioning these is limited owing to high dressing tool wear, long process time, low form flexibility, induced damage grains. Wire electrical discharge (WEDM) an alternative method superabrasive with electrically cond...
