The purpose of the carriage stop on a duplicating machine is to keep the carriage from moving too far. This component serves an important function by limiting the range of motion of the carriage as it operates. It ensures that the cutting tool does not travel beyond the necessary distance required for duplicating a key, effectively preventing potential damage to the machine, the key blank, or the cutting tool itself. By setting the carriage stop at a specific point, the operator can produce consistent and accurate cuts without risking overextension that could lead to inaccuracies in key duplication or equipment malfunction.

In contrast, maintaining the correct distance from the blank key addresses an aspect of precision rather than controlling movement. Securing the key during the cutting process relates more to stability during operation rather than preventing excess movement. Preventing damage to the vise is important, but it is not the primary function of the carriage stop, which is specifically designed to regulate the movement of the carriage.
