High efficiency cutting is a systematic engineering. By selecting machine tools and process equipment with good technical conditions, sufficient power and rigidity, the rigidity of the whole cutting system can be improved, the cutting conditions can be improved, and the deformation of parts can be avoided or reduced. The machinability of the machined materials is improved by reasonably distributing the machining allowance in each stage and conducting proper heat treatment on the machined materials. Through reasonable choice of tool geometry Angle and effective cooling measures, the cutting performance of tool materials can be given play to, and a certain degree of tool durability can be guaranteed to make the cutting smooth. At the same time, obtain higher processing efficiency and processing quality.
Four Simplified Steps
The new ideas about advanced machining functions are based on the idea that any five-axis machining function, however complex, can be defined in a few simple steps. Mold manufacturers have adopted the tried-and-true method of setting up mold production procedures:
(1) Processing area and processing sequence. This step, based on the complexity of the shapes of the parts, is often the easiest to inspire a skilled mechanic.
(2) What shape should the tool path take in the machining area? Should the tool be machined in front and back or top and bottom order according to the parameterized lines of the surface, with the surface boundary as the guide?
(3) How to guide the tool shaft so that it is consistent with the tool path? This is important for the quality of the surface finish and whether shorter hard cutting tools are used in smaller Spaces. The tool maker needs to have adequate control over the tool, including the rake Angle when the tool tilts. In addition, it is necessary to consider the angular limits of many machine tool workstations or tool holders when they are rotated. For example, there are limits to how much a milling/turning machine can rotate.
(4) How to convert the cutting path of the cutter? How to control the displacement of the tool due to reset or generated and the displacement of the tool must be generated between the machining areas at the starting point of the tool path? The displacement produced by the conversion process is critical in the production of the dies, which can eliminate the traces of the identification line and the tool (which can be removed by subsequent manual polishing).
