Further, the diamond wire 8 is not coiled on the additional wheel train, and is coiled between two adjacent wheels at other positions by no more than one turn.
According to 17 designed different winding paths, the method for measuring the additional tension of each path is the same, the types of the used diamond wires 8 are the same, the equipment motion parameter setting is the same, and when each path measures the additional tension, the following steps are repeated:
s1, the same coil of diamond wire 8 was sampled at least 5 times at intervals, and the average ultimate breaking tension of the sample was measured and recorded as F.
S2, winding the diamond wire 8 on the wheel train according to a designed path, and ensuring that the diamond wire 8 does not roll when passing through the additional wheel train between the guide wheel and the cutting wheel 3, and the roll between two adjacent wheels at other positions does not exceed 1 circle. The diamond wire 8 is easily broken when being wound too much, and the detection of the additional tension is influenced.
S3, setting a tension F1 in a non-cutting state, presetting the reciprocating motion of the diamond wire 8 on a gear train mechanism because the operation of the device is generally a reciprocating operation, setting the operation time of the gear train mechanism as t, increasing the magnitude of the set tension to F2 if the diamond wire 8 is not broken within t time, operating the device again for the t time, and continuing to increase the magnitude of the set tension to F3 if the diamond wire 8 is not broken within t time, and … are carried out according to the steps until the diamond wire 8 is broken within the operation time of t under the Fn tension.

And S5, replacing the designed path, setting the same motion parameters by using the same diamond wire 8, repeating the steps, and recording the additional tension values of other paths.
And S6, comparing the additional tension values in different paths, and further judging the influence of the additional gear trains in different paths on the additional tension.
A method for evaluating the influence of low-precision wheels on the additional tension of a diamond wire 8 is characterized in that the low-precision wheels are used for replacing additional wheels of an additional wheel train in a wheel train mechanism, and the change of the additional tension after replacement is calculated, so that the influence of the low-precision wheels on the tension of the diamond wire 8 is evaluated. For the diamond wire 8 supported by the cutting wheel 3 to cut the revolving body, the revolving body usually has a large revolving error due to the precision of the wheel body, and the fluctuation of the diamond wire 8 is caused, thereby affecting the cutting quality. Therefore, the additional wheel is rotated and unbalanced by changing the unbalance amount of the additional wheel in the additional wheel train of the wheel train mechanism, and the adverse effect of the unbalance of the low-precision wheel on the additional tension of the diamond wire 8 is simulated. In addition, whether the precision of the replaced additional wheel meets the actual production requirement or not can be evaluated by replacing the additional wheel under the condition that other test conditions are not changed.
