Which component is used to prevent formation of long chips during turning?

• A. Chip breaker
• B. Depth limiter
• C. Shock absorber
• D. Lubricant bath

Answer: (A)

Controlling chip length in turning is essential for safe, smooth operation. A chip breaker is designed into the cutting tool to interrupt and fracture the forming chip as it exits, producing shorter, more manageable pieces rather than a long continuous strand. This helps prevent chips from curling around the tool or workpiece, reduces the risk of tool clogging, and improves surface finish by allowing the chip to leave cleanly. The breaker works with a groove, edge, or ramp that the chip encounters as it curls, forcing it to snap. The other options don’t influence chip length: a depth limiter restricts how deep the cut can go, a shock absorber dampens vibrations or tool deflection, and a lubricant bath mainly reduces friction and cooling. So the component that prevents long chips is the chip breaker.
