If l=b=s=m=2 and t=Find the value of v. l=length of the cutting stroke in mm, b=width of the work in mm, s=feed in mm, v=cutting speed in mm/minute, m=the ratio between return time to cutting time and t=machining time in minute.
Correct Answer: D — 0.06
Explanation:
From the formula, t= lb(m+1) / (1000vs). From this equation, we can easily calculate the value of v by putting all mentioned values.
