OBRABOTKAMETALLOV MATERIAL SCIENCE Том 23 № 3 2021 EQUIPMEN . INSTRUM TS Vol. 6 No. 2 2024 of D16 aluminum alloy and is type 6, with body dimensions of 200×20×4×29×76 mm. This wheel has a maximum permitted cutting speed of 50 m/s. This wheel is proposed as a graphic model and shown in Figure 3. Fig. 3. Graph-based model of the wheel type 6A2 200×20×4×29×76 AC6 200/160 B2-01 The present model is a simplified matrix B1, which contains only those elements present in the specific model of the wheel. The components not included in the design are not considered, which reduces the size of the matrix: 111 121 122 123 124 126 1321 13214 1423 152 1652 1 1 2 3 X 1 1 1 1 1 1 1 1 1 1 1 = 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 X X X X X X X X X X X X X Â 216 221 222 223 224 225 228 229 2210 2322 3131 0 0 0 0 0 0 0 0 0 0 0 . 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 1 X X X X X X X X X X X In order to gain further insight, we may now consider another design of a modular abrasive tool. This wheel has been specifically developed for diamond-abrasive machining [8, 51–52] and is presented in Figure 4. This wheel has an interrupted (segmental) abrasive part in the form of cylindrical heads fastened in the body by radial screws. The abrasive part is made of Bakelite B2-01 bond and synthetic diamond. The body is made of steel and is type 36 with body dimensions 250×10×7×34×51 mm. This wheel has a maximum permitted machining speed of 270 m/s. This wheel is represented by a graphic model and is shown in Figure 5: Now, by analogy, we construct the matrix B2 describing this wheel construction: 112 121 122 123 124 126 1321 13214 1423 152 1652 1 2 2 3 X 1 1 1 1 1 1 1 1 1 1 1 = 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 X X X X X X X X X X X Â X X
