In structural dynamic analysis of the CNC engraving and milling machine, as with the quality of concrete structure and agency has a lot to do with the vibration characteristics of, therefore retained the equal axis stepper motor frame and the quality of the cube instead of stepping motor.
Screw part only under the axial force in the transmission, can replace with cylindrical rod, its structure as shown in the figure below.
In the contact area of nc carving and milling machine cylindrical guide and setting of frictional contact between bushing (
摩擦)
, friction factor is 0.
03, the rest of the surface is Bonded.
The grid division and static analysis are basically the same.
> carving and milling machine two bottom completely constraint ( FixedSupport) 。 If use & lt; 3. 175 mm double flat milling processing, milling cutting force calculation formula are used to get the load size.
