The cut square can reflect the displacement accuracy of the machine tool coordinate, the smoothness of the running of the guide wheel, the system hysteresis of X and Y, and the fidelity of the feed and actual displacement. Any problems related to the accuracy of the machine tool are reflected in the cut and can not be artificially concealed.
The cuts should be analyzed in the following aspects:
1. The two straight faces parallel to the X-axis are small in size and slow in feed rate, indicating that the axial deflection of the guide wheel is relatively large, and the slit becomes large. The two straight faces parallel to the Y-axis are small in size and slow in feed rate, indicating that the radial deflection of the guide wheel is large and the cutting degree becomes large.
2, 45 degrees two parallel slopes, the size is too small, indicating that the Y-axis system has a large backlash, the difference is about twice the difference. Two parallel slopes of 135 degrees, the size is too small, indicating that the X-axis system has a large backlash, and the difference is about twice the difference.
3. On the 45th and 135th slopes, the seesaw pattern with the pitch of the lead screw appears, and the distortion of the feed displacement occurs on the X or Y axis, indicating that the X or Y axis screw pushes the working end of the pallet to jump or be distorted. This texture and cycle relationship can only be found on 45 and 135 degree slopes. The 45-degree and 135-degree sloping planes have the stencil pattern of the motor gear as the cycle, indicating that the motor gear is not equally divided or eccentric. This fault is not visible in the straight line, and the rounding does not clarify its periodic relationship.
4. The weight of the two straight slabs parallel to the X axis indicates that the wire does not follow a trajectory in the Y-axis direction when running up and down. (The extension line of the "V" groove of the upper and lower guide wheels is not a line, so the wire is commutated into a periodic slab pattern.) The two straight slabs are parallel to the Y axis, indicating that there is no way in the X direction when going up and down. There is a big difference in tension between the upper and lower sides. (The wire is commutated into a periodic crepe pattern.)
5. The angle between the 45-degree inclined surface and the 135-degree inclined surface is greater than or less than 90 degrees, which indicates that the vertical difference of the X and Y guide rails is different. The four straight faces are not perpendicular but the opposite sides can be parallel, and the difference is about the stroke. Double the verticality error. The inconsistency between the lower two ends of the cutting surface indicates that one of the upper and lower guide wheels has a significantly degraded positioning effect on the molybdenum wire.
As mentioned above, it is difficult to expose these to any other shape. Therefore, cutting the eight sides is indeed the best way to check the overall accuracy of the machine.
