A pipe cutting machine capable of cutting saddles and mitres and combinations of saddles and mitres is disclosed. The machine uses the rotation of the pipe itself to power a cam drive assembly. The cam drive assembly powers a saddle cam and a mitre cam. The saddle cam and the mitre cam may be set such that a specific mitre cut, saddle cut, or combination of saddle and mitre cut may be accomplished. A cable assembly translates the rotation of the saddle and mitre cams to a torch carriage. The torch carriage in turn translates its movement concurrently to the torch itself, thereby cutting the exact saddle, mitre, or combination of saddle and mitre cut desired.
