rdb dastgohida ishlov berish uchun texnologik jarayon mashrutini ishlab

H yuzad 4 ta teshik parmalansin. Kesuvchi asbob: Spiral parma.T15K6 markali
Kesish chuqurligi: t=D/2 = 16/2=8 mm
Surish miqdori , kesish tezligi V_T, kesishdagi quvvat N_T, O’q bo’yicha kuch P_T parmalash qiymatlari aniqlanadi: ([3] 46-karta, 128-b)

V_T = 25.5 m/min N_T = 0.64 Kvt
Kesish maromini korrektirovka qilish formulalarini ([3] 52-karta, 141-b) va
korrektirovka qiluvchi koeffitsientlarni aniqlash ([3] 53-karta, 142-148-b):
