In CNC milling, collision detection and avoidance are critical for safeguarding machine spindles, tools, workholding fixtures, and the workpiece.
In CNC milling, collision detection and avoidance are critical for safeguarding machine spindles, tools, workholding fixtures, and the workpiece. A collision is defined as any unplanned contact between the non-cutting elements of the tool assembly (shaft, holder, spindle nose) or the cutting portion itself with the workpiece, stock, or fixtures during rapid positioning.
To calculate clearances accurately, Fusion 360 divides the tool assembly into three distinct geometric regions:
Fusion 360 provides specific options to manage collision parameters, primarily split between the Setup (for fixtures) and the Tool/Passes tabs (for shaft and holder clearances).
