The choice of tool is in the NC programming man-machine interaction state. Should be based on the processing capacity of the machine, the workpiece material performance, processing procedures, cutting the amount and other related factors correctly selected tool and handle.
The general principle of tool selection is: easy to install and adjust, good rigidity, durability and high precision. To meet the processing requirements of the premise, try to choose a shorter handle to improve the rigidity of tool processing.
When selecting a tool, make the size of the tool compatible with the surface size of the workpiece being machined:
Flat parts peripheral contour processing, often using end mills;
Milling plane, should be selected carbide cutter cutter;
Processing the boss, groove, the election high-speed steel end mill;
When processing the rough surface or the roughing hole, select the corn cutter with the carbide blade;
Dimensional surface and variable bevel contour contour of the processing, often using ball end cutter, ring cutter, tapered cutter and disc cutter.
In the free surface processing, the end of the ball tool cutting speed is zero, therefore, in order to ensure the processing accuracy, cutting line spacing is generally made very close, so the ball head is often used for surface finishing. The flat head tool in the surface processing quality and cutting efficiency are better than the ball knife, so, as long as the guarantee is not cut under the premise of both the rough surface processing or finishing, should give priority to the choice of flat knife.
It is worth mentioning that the durability and accuracy of the tool and the tool price great! It should be noted that, in most cases, the choice of good tool although the increase in tool costs, but the resulting processing quality and processing efficiency, you can make the entire processing costs greatly reduced.
