G61 & G64 - Path Control Mode Commands

G61 and G64 are path control mode commands that determine how the machine handles transitions between consecutive motion commands. These commands significantly affect the smoothness and accuracy of the resulting tool path:

• G61 (Exact Path Motion): Forces the machine to come to a complete stop at each programmed point before proceeding to the next
• G64 (Continuous Path Motion): Allows the machine to blend motion between consecutive moves for smoother operation

The choice between these modes involves a tradeoff between accuracy and speed. G61 provides maximum positional accuracy but can result in jerky motion, while G64 provides smoother motion but may deviate slightly from programmed points during blending.
