What are the general requirements of cnc rapid prototyping technology?


Cnc rapid prototyping CNC parts machining center spindle speed, feed speed and cutting speed are generally determined by the tool, and the setting amount of different tool parameters for processing the same material will also be different. But the tool will provide the parameters set at the time of purchase. For example, different imported tools provide parameters for processing different materials, which can give the maximum feed rate, cutting amount and cutting speed.

Cutting speed, feed speed and cutting depth are the three elements of CNC parts machining and cutting conditions. If these elements are not well controlled, it will cause tool damage. As the cutting speed increases, the temperature of the cutter head will increase, resulting in mechanical, chemical, and thermal wear.

If the cutting speed is increased by 20%, then the tool life will be reduced by 1/2. The relationship between the feed conditions for CNC part machining and the wear on the back of the tool is generated within a very small range. However, if the cnc rapid prototyping feed rate is high and the cutting temperature is increased, then the rear wear is also likely to be large.

Its impact on the tool is less than the cutting speed, and the cutting depth has a greater impact on the tool than the cutting speed and feed, but when the cutting depth is small, a hardened layer will be formed on the material being cut, which will also affect the tool's Service life.
In the process of CNC parts processing, generally need to choose the cutting speed according to the processed material, hardness, cutting state, material type, feed speed and cutting depth. The selection of suitable processing conditions is generally based on these factors.

CNC parts processing generally requires a reasonable choice of fixtures, and the parts should fully meet the needs of the machine to reduce unnecessary positioning errors, so select special fixture clamping tools.
When CNC parts are processed for face milling, non-reground carbide end mills or end mills should be selected. In general milling, try to use two passes. The first pass is preferably rough milling with an end mill and continuous passes along the workpiece surface.
