It should be noted that, in the embodiments of the present application, reference is made to fig. 4:
for example, in general, the thickness of the stock sheet of a furniture processing plant is determinable, assuming δ, and the inner perimeter C of the hollow cylindrical member(inner perimeter)Then, by means of CAD drawing software, the inner arc length of the cross section of the largest hollow cylindrical component in a plate with the thickness of δ can be measured as AB, and then it can be determined that N plates with the thickness of δ are needed, then the central angle of each plate with the thickness of δ, that is, the central angle of the inner arc length AB, can be obtained by calculation, and the calculation formula is:
∠1=360°÷N;
since N is C(inner perimeter)÷AB;
So, angle 1 is 360 °/(C)(inner perimeter)÷AB)=360°×(AB÷C(inner perimeter));
In the formula, the angle 1 represents the central angle of the inner arc length AB, and N represents the number of plates.
According to the corresponding geometric relationship, the delta COD is an isosceles triangle, and the internal cutting angle of the plate can be calculated by the following calculation formula:
∠2=(180°-∠1)/2=90°-180°/N;
in the formula, the angle 2 represents the internal cutting angle of the plate.
It is understood that the outer cutting angle of the plate material and the inner cutting angle are in a complementary relationship, and therefore, the outer cutting angle can be calculated by the following calculation formula, namely, the machining angle of the blade in machining production:
∠3=180°-∠2=180°-(90°-180°/N)=90°+(180°)/N=90°+(180°)/(C(inner perimeter)÷AB);
In the formula, the angle 3 represents the external cutting angle of the plate, namely the processing angle of the blade during processing production.
It should be noted that, as shown in the above embodiments, the splicing angle of the plate is the internal cutting angle of the plate.
It should be noted that specific contents and beneficial effects of the technical portion of the present embodiment can be referred to the embodiments described herein, and are not described herein again.
