CNC Machining Programming:Four Knowledge Points of CNC Machining Programming Technology Worth Learning

CNC machining is increasingly used in today's CNC machining parts manufacturing plants. The reason behind the success of these CNC machining machines is obvious-they combine CNC milling and CNC turning, so that complex parts can be CNC machined in one operation, which greatly reduces the CNC machining time.

Usually, long-term preparation will lead to high cost of CNC machining parts, especially in small batch production. In addition, CNC milling guarantees high CNC machining accuracy, because there is no need to process CNC machined parts in multiple operations, which means less processing of parts in different CNC machining stages. These two factors provide a competitive advantage, for many CNC machining parts companies to manufacture complex, high-precision CNC machining parts, the quantity is 1-100 pieces.

The development of CNC machining technology also puts forward higher requirements on CNC machining programming technology, and it is also a bottleneck that restricts the actual production and application of CNC machining machine tools. Compared with the traditional CNC machining programming technology, the programming difficulties of CNC machining machine tools are mainly reflected in the following aspects.

(1) There are many types of manual CNC milling.

For most craftsmen, it is not only necessary to master the programming methods of various CNC machining methods such as CNC machining turning, multi-axis CNC milling, and drilling, but also to accurately determine the connection between the CNC machining processes and the way of advance and retreat. Therefore, when programming for NC machining, it is necessary to intuitively understand the distribution of NC machining model and NC machining allowance in the current NC machining process in order to facilitate the programming of the next process and the setting of advance and retreat tools.

(2) The procedures of serial sequence and parallel sequence must be determined strictly in accordance with the process route.

From wool to finished products, many CNC machining parts can be processed in CNC machining centers. Therefore, the result of the processing program must be consistent with the process route. At the same time, multi-channel parallel processing needs to be considered comprehensively in the process of CNC machining programming.

(3) For some functions of CNC machine tools, the current general-purpose CAM software does not yet support them.

Compared with the traditional single-equipment CNC machining, the machine tool motion and CNC machining functions of combined turning-milling combined machining are much more complicated. The existing general-purpose CAM software is not enough to fully support the programming of advanced functions such as online measurement, sawing, automatic feed, and tail box control. Therefore, programs written with general-purpose CAM software still require a lot of manual or interactive methods to realize CNC machining.

(4) Integration of CNC machining programs. At present, the NC machining programs compiled by general-purpose CAM software are independent of each other.

In order to realize complex CNC machining parts such as CNC turning and milling, it is necessary to integrate and integrate these independent CNC machining programs. This integration must be guided by the process route of the components. First determine which programs are parallel, and then determine the processing sequence of different CNC machining methods, and give accurate tool change, card change, benchmark conversion, advance and retreat instructions. Wait.

One of the key capabilities of multifunctional CNC machining CAD/CAM software is its ability to manage CNC milling and CNC turning. Most software solutions on the market today provide very powerful CNC milling strategies, but they are less capable of steering. In fact, Missler software has a wealth of experience in development, starting from the early days, and today is one of the leading suppliers of CAD/CAM software for steering strategies.

On the basis of the existing general CAD/CAM software, it is a more realistic solution to develop a special programming system suitable for CNC machining parts technology and compound machining equipment. This aspect reduces the repeated investment in software procurement, and at the same time avoids the inability to reuse process knowledge and complex staffing due to inconsistent CNC machining programming platforms.
