Lead-in In CNC machining, laser cutting, and other subtractive manufacturing processes, a lead-in is a designated path or trajectory that the cutting tool or laser follows as it begins to engage with the workpiece. The lead-in serves several purposes, including establishing an entry point for the cutting tool or laser beam, reducing the likelihood of burrs or surface defects, and improving cutting accuracy and efficiency.
Lead-ins are carefully programmed and positioned to ensure smooth and controlled entry into the workpiece, minimizing the risk of tool chatter, workpiece deflection, or damage to critical features. Different lead-in strategies, such as straight lines, arcs, or spirals, may be used depending on the material, geometry, and cutting conditions. |
