MyCNC Constant Velocity Mode (CV)

In classic “Exact Stop” mode CNC control Toolpath planner adds Acceleration/Deceleration for each g-code command block.

For Constant Velocity (CV) mode Toolpath planner tries to make a motion without stops. Figures below demonstrate Speed profile and Toolpath for Exact Stop and CV Mode.

Fig.1 Exact Stop Mode Toolpath and Speed profile example.

Fig.2 CV Mode Toolpath and Speed profile example.

In CV Mode Control software Toolpath planner reduces cutting speed on corners to keep Toolpath tolerance in a range given in “CV tolerance” in “Motion” configuration dialog

S-curve Speed profile is implemented in myCNC for CV-mode. It makes a smooth motion for all axes and significantly reduce machine vibration, step loss and cutting time.
