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 development of turning center has a considerable part of rotating parts (someone estimates that it accounts for about 1/2). In addition to turning, operations such as milling, drilling, and tapping are also required. In addition, the pro....
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....
External turning as an example, there are three turning components: main turning force Fc (Fz), depth resistance Fp (Fy) (also called radial force), feed resistance Ff (Fx) (also called axial force). The main turning force is the most import....
