CNC parts processing center how to process parts

<p>&nbsp; CNC machining has good flexibility and high degree of automation. It is especially suitable for processing curves and curved parts with complex contours, as well as complex box and prism parts with a large number of holes and grooves. In the case of multi-variety and small batch production, CNC machine tools are used. Processing can obtain higher economic benefits.</p><p> The processing of large <a href="https://www.qyprecision.com/" rel="noopener noreferrer" target="_blank"><a href="https://www.qyprecision.com/" target="_blank">CNC parts</a></a> processing technology is basically the same as that of ordinary processing, but it has its own characteristics. Therefore, when designing the CNC machining process of parts, it is necessary to follow the CNC machining with good flexibility and high degree of automation, especially suitable for processing curves and curved parts with complex contour shapes, as well as complex box and prism parts with a large number of holes and grooves. In the case of multi-variety and small-batch production, the use of CNC machine tools can achieve higher economic benefits.</p><p>&nbsp;&nbsp;&nbsp;The determination of the tool setting point and tool change point of a large CNC part machining center. The tool setting point is the starting point of the tool movement relative to the workpiece during CNC machining. Since the program is also executed from this point, the tool setting point is also called the starting point or starting point of the program. When programming, you should first consider the choice of tool setting point. When the machining accuracy is not high, some surfaces on the workpiece or fixture can be used as the tool setting surface; when the machining accuracy is high, the tool setting point should be selected as much as possible on the design basis or process basis of the part, such as positioning with holes Parts, it is more appropriate to take the axis of the hole as the tool setting point. The tool setting point must have a certain coordinate relationship with the positioning reference of the workpiece, so as to determine the relationship between the machine tool standard system and the workpiece coordinate system. The selection of tool setting points should facilitate the calculation of coordinate values ​​and make tool setting convenient. When setting the tool, the tool setting point and the tool position point should coincide. The so-called tool point refers to the intersection of the tool axis and the bottom of the tool for flat-bottom end mills; for the ball-end milling cutter, it refers to the center of the ball head; for turning tools, it refers to the tip; for drills, it refers to the tip; The wire electrode cutting machine refers to the focus of the wire electrode axis and the part surface. When the tool needs to be changed during the process, the tool change point should be specified, and the position of the tool change point should be set according to the principle that the workpiece, fixture and machine tool should not be injured during the tool change.</p>
