Subject: [TN] Drilling questions

Can someone explain to me what the Letter/Numbers in a drill program mean?

The following is a line from a drill program

C0.0098F036S110.B0800Z-0.012H350

C0 = Starts the program
0098 = Drill (tool) size
[John Parsons] C0.0098 = tool diameter (inches)
F036 = Feed, but what is 036?[John Parsons]  Feed Rate (ips)
S110 = 11000 or 110000 RPMs[John Parsons]  RPM (110000)
B0800 =[John Parsons]  Macro Code ?? (we never use these so I can't provide
more detail)
Z-0.012 =[John Parsons]  Z-axis height adjustment from datum
H350 = 350 drill hits[John Parsons]  Max hits allowable for this tool before
change

Also, can someone provide a simpler method for determining chip load?[John
Parsons]  I have attached a calculator that you may find useful.
