CNC automatic programming method

How many methods are there for NC machining programming?

Automatic programming of CNC machining
The automatic programming of CNC machining is also called computer-aided programming, to jest, most or all of the programming is done by the computer. Such as completing the calculation of coordinate values, compiling part processing procedures, automatically outputting and printing processing procedures and preparing control media.

Milling impeller processing of milling machine

Solve the deformation of parts in high-speed milling

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 vibration will destroy the relative correct position of the tool and the workpiece, and reduce the surface processing quality and milling efficiency. For a long time, cutting chatter has been a major research topic in the machinery manufacturing industry and milling processing.

Ultra-presná technológia frézovania

Ultra presné CNC frézovacie diely

Ultra presné rezanie začalo technológiou SPDT, ktorý je podopretý vzduchovými ložiskovými vretenami, pneumatické šmýkačky, vysoká tuhosť, vysoko presné nástroje, spätná kontrola, a reguláciu teploty prostredia na získanie drsnosti povrchu na nanoúrovni. Väčšinou sa používajú diamantové frézy, ktoré sú široko používané pri spracovaní medených plochých a asférických optických prvkov, plexisklo, plastové výrobky (ako sú plastové šošovky fotoaparátov, kontaktné šošovky, atď.), keramiky a kompozitných materiálov.

CNC machining of prismatic parts

Sústruženie a frézovanie prizmatických dielov

The machining center performs multi-process (sústruženie, frézovanie, vŕtanie, nudný, tapping, atď.) and multi-face composite processing on prismatic parts through automatic tool change and table indexing. Practice has proved that the composite machining center is indeed beneficial to solve the shortcomings of long delivery time, low resource utilization, more products in process and slow capital turnover of small and medium-sized machinery manufacturing enterprises. Turning and milling combined processing has thus gained more and more common applications in industrial production.

What are difficult-to-machine materials?

Difficult-to-machine materials are materials with poor turning and milling workability. Performance of this material is greater than or less indicators (HB> 250, σb> 1000 MPa, δ> 30%, αk> 100 MPa, K <41.8 W / mk) one or more, are all difficult to cut materials. It can also be measured by phenomena in the cutting process (cutting force, cutting heat, tool wear and tool durability, processed surface quality and chip control, etc.).

Problems when cutting difficult-to-machine materials

Cutting is roughly divided into turning, frézovanie, and center-tooth-based cutting (end face cutting of drills and end mills, atď.). The cutting heat of these cutting processes has different effects on the cutting edge. Turning is a continuous cutting, the cutting force on the tip does not change significantly, and the cutting heat continuously acts on the cutting edge; Milling is a kind of intermittent cutting, and the milling force is intermittently acting on the tip of the blade, and vibration will occur during milling. The heat effect on the cutting edge is the heating during cutting and the cooling during non-cutting alternately, and the total amount of heat received is less than during turning.
