this is the post of the machine i working on https://www.physicsforums.com/threads/force-required-for-cutting-sheet-metal.946971/

thanks anorlunda you are right i have many more question and i will describe it here to get the right answer but i just wait to order my questions thanks again

what you meant by continuous cutting ? Can you tell me will it change it i change the cutting process ?

you are right first i will design a machine that cut the metal sheet to parts by hand , after i will get a roll of sheet metal and cut it to specific lengths automatically

the tool will be manual now , but in the future will be automatic what you mean by continuous or cyclic ? i designing the equipment about the longevity and maintenance it depends on the cost

hello every one can you help me in selecting the material to be used in the blade of cutting machine which will be used to cut galvanized sheet metal

this is the electric motor vision and ,but not the final decision

this dimension is about 100 mm

what dimension you need ?

this is the design of the shear machine

but if so the area of this triangle is too small because the sheet thickness is 1.5 mm so if the area is 8 mm2 , UTS is 370 n/mm2 then the force = 0.7*370*8 = 2072 N is it right ?

the area in blue will change from start from 1300 mm at the start of cutting process and ends at the end of the cutting process and the change will be in mm , and according to this equation the value of shear force will change as the area changes ?

this is my best guess wish you help me more thanks

CAN YOU MAKE IT MORE CLEAR SORRY

thanks for reply ,but if the sheet to be cut is 1.25 mm thickness and 1300 mm and have UTS of 350 n/mm2 and the angle blade is 15 degree so what is the cutting force required ? will it be 420875 N or less or more ?
