Cutting is roughly divided into turning, milling, and center-tooth-based cutting (end face cutting of drills and end mills, etc.). The cutting heat of these cutting processes has different effects on the cutting edge. Turning is a continuous....
Difficult-to-machine materials are materials with poor turning and milling workability. Performance of this material is greater than or less indicators (HB 250, b 1000 MPa, 30%, k 100 MPa, K 41.8 W / mk) one or more, are all difficult to cut....
The machining center performs multi-process (turning, milling, drilling, boring, tapping, etc.) and multi-face composite processing on prismatic parts through automatic tool change and table indexing. Practice has proved that the composite....
Turning, milling complex development of CNC machining technology, CNC programming techniques also put forward higher requirements. This is also a key link that restricts turning and milling compound processing equipment in actual production....
In the early 1960s, due to the gyroscopes used in aerospace, the drums and disks used in computers, and the polygonal prism parts used in optical scanning. Large-diameter non-circular curved mirror parts for high-power laser nuclear fusion d....
Titanium alloy has high strength, high fracture toughness, good corrosion resistance and weldability. Because it is more difficult to process than ordinary alloy steel, titanium alloys are generally considered to be difficult to process mate....
In milling, an important characteristic of titanium alloys is extremely poor thermal conductivity. Due to the high strength and low thermal conductivity of titanium alloy materials, extremely high cutting heat (up to 1200C if not controlled)....
Parts finishing is an algorithm based on curved surfaces. For multi-curved models, the lifting of the milling cutter should be reduced as much as possible. This requires that the generated milling tool path be within the same angular range o....
The high-speed milling system is a complex dynamic system, which is prone to chatter vibration when machining thin parts. Flutter is a very strong relative vibration between the tool and the workpiece during the milling process. This kind of....
One hundred years ago, high-speed steel cutting tools began to be used, and the cutting speed for milling ordinary steel was only 25-30m/min. Compared with carbon tool steel and alloy tool steel, the processing at that cutting speed is high-....
