Cycle Syntax
G70 P10 Q11 F0.15;
Parameter Explanation
P / Q – Start and End block numbers (must match the ones used in G71 or G72 roughing).
F – Feed rate for finishing. This overrides the previous feed if used.
Key Notes
🔹 G70 cycle is used to finish the profile after a roughing cycle like G71.
🔸 It reuses the finish allowance from the roughing cycle – you cannot provide U/W again.
🔹 Multiple G70 blocks can be used if you need to finish different sections.
🔸 Use P and Q to define which section of the program should be finished.
🔹 This is typically a single-pass clean-up cut.
