calculator. Writing code is really easy and fun. I have used it to solve
lots of problems. Here is the code. It is in python 2.7. This language is
the easiest to understand and is quite close to the english language. It is
free to download!
running=1
print "Lathe Speed Calculator -Imperial- by Mr.Meker"
raw_input("Press <enter> to continue")
while running==1:
print """
Aluminum (1)
Mild Steel (2)
Brass (3)
Custom Speed (4)
"""
mat=input("Choose Material: ")
if mat==1:
print "Aluminum"
elif mat==2:
print "Mild Steel"
elif mat==3:
print "Brass"
elif mat==4:
sfm=input('Enter surface feet per minute: ')
else:
print "invalid material"
break
if mat==1 or mat==2 or mat==3:
print """
HSS (1)
Carbide (2)
"""
cut=input("Cutter type: ")
if cut==1:
print "Cutter: HSS"
elif cut==2:
print "Cutter: Carbide"
else:
print "invalid cutter type"
break
dia=input("Enter Diameter (inches): ")
if mat==1:
if cut==1:
sfm=300
if cut==2:
sfm=2800
if mat==2:
if cut==1:
sfm=175
if cut==2:
sfm=850
if mat==3:
if cut==1:
sfm=325
if cut==2:
sfm=1100
rpm=12*sfm//(3.14*dia)
print "RPM is: ", rpm
running=input("Run again? 1/0 ")
and there it is!
