RISA New Approach to Planning Plungers Paths for Efficient 2آ½ Axis Computer Numerically Controlled Plunge Milling of Complex Pockets With Islands
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Plunge milling is an effective roughing operation, especially in pockets roughing, because it can efficiently remove a large amount of stock material without high manufacturing costs. However, plunge milling of complex ...
An Accurate and Efficient Approach to Three-Dimensional Geometric Modeling of Undeformed Chips for the Geometric and the Physical Simulations of Three-Axis Milling of Complex Parts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To pursue high-performance computer numerical control (CNC) milling of complex parts, it is crucial to simulate their machining process geometrically and physically with high fidelity beforehand. The geometric simulation ...
A Generic and Efficient Approach to Determining Locations and Orientations of Complex Standard and Worn Wheels for Cutter Flute Grinding Using Characteristics of Virtual Grinding Curves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As an important feature of cutting tools, flutes determine rake faces of their cutting edges, their rigidity, chip breaking, and chip space. In industry, flutes are often ground with standard wheels of simple shape (e.g., ...
A New Method of Designing the Tooth Surfaces of Spiral Bevel Gears With Ruled Surface for Their Accurate Five-Axis Flank Milling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The advantages of the five-axis flank milling of (developable) ruled surfaces include that (1) the machined surfaces could be very accurate and smooth and (2) the machining efficiency is high. Currently, spiral bevel gears ...
An Automated and Accurate CNC Programming Approach to Five Axis Flute Grinding of Cylindrical End Mills Using the Direct Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In solid carbide endmills, the flutes significantly affect the tool's cutting performance and life, and the core radius mainly affects the tool's rigidity. The current CNC programming techniques can correctly determine the ...
Constructing Process Models of Engine Blade Surfaces for Their Adaptive Machining: An Optimal Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a new blade manufacturing process, manufacturers precisely forge blade billets with the blade suction and the pressure surfaces within tolerance. After that, only two blade edge billets should be machined to the leading- ...
A Reliable and Efficient Approach to Numerically Controlled Programming Optimization for Multiple Largest Tools Cutting Blisks Patch by Patch in the Blisks' Four-Axis Rough Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As an important component of gas turbine engines, a blisk (or an axial compressor) is complex in shape. The pressure and suction surfaces of the blisk blades are designed with free-form surfaces, and the space (or the ...
A New and Accurate Mathematical Model for Computer Numerically Controlled Programming of 4Y1 Wheels in 2آ½ Axis Flute Grinding of Cylindrical End Mills
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solid carbide cylindrical endmills are widely used in machining, and their helical flutes are crucial to their cutting performance. In industry, the flute is simply defined with four key parameters: the helical angle, the ...
