Travel Speed

Travel speed is the linear rate at which a CNC axis, gantry, or machine table moves from one position to another, commonly called rapid traverse or G00 motion. It is non-cutting move speed used between toolpath segments. Actual travel speed is limited by configured axis velocity and acceleration, so short segments may not reach commanded speed.

On the shop floor, travel speed governs every non-cutting move: rapid retracts after a cut, repositioning between pockets, tool changes, and moving from one part to the next on a nesting table. Programmers call this G00 in the code, but the control's configured axis velocity and acceleration are the real leash. A long G0 run may hit the machine's top end, whereas a short hop between features spends most of its time ramping up and down. Operators rely on rapid override on the panel to slow things down when setups are tight. When travel speed is too aggressive, toolpaths still cut fine, but the machine can shudder, stall, or collide with clamps, vacuum pods, or spoilboard pins. Good path planning sets safe Z heights and avoids unnecessary rapids, and technicians tune axis parameters while watching long moves for noise and position loss.

• ⚠️Axis stall or missed steps: When commanded travel exceeds what the machine can physically deliver, the motor screeches, stalls, or loses position, especially on smaller machines, leaving every subsequent toolpath shifted from true coordinates.
• ⚠️False productivity gains on short moves: Raising the maximum travel speed does little for cycle time because most moves are too short to reach full velocity; the machine spends its time accelerating and decelerating instead of moving at speed.
• ⚠️Collision risk from aggressive rapids: A fast G00 move can crash into clamps, spoilboards, vises, dust boots, or part edges when safe Z heights, fixture clearance, or retract logic are incorrect; the result is immediate mechanical damage.
