If l=b=s=v=3 and m=Find the value of t. 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: B — 0.0125
Explanation:
From the formula, t= lb(m+1) / (1000vs), we can easily calculate the value of t by putting all these values in given equations.
