What could worn wipers allow to get between the carriage and the ways?

1. Dust

2. Chips

3. Mist

4. Oil

The correct answer is: Chips

Worn wipers can lead to the infiltration of chips between the carriage and the ways, which is critical to understand in the context of machinery maintenance and operation. Wipers are typically designed to keep debris, such as chips produced during machining processes, from accumulating in the ways of a machine. These chips can interfere with the smooth operation of the machine and cause wear and damage. If the wipers are worn down or not functioning properly, they are unable to effectively perform their task, resulting in the potential for chips to enter the carriage area. This accumulation can lead to inaccuracies in machining, reduced efficiency, and increased wear on both the carriage and ways. The other options like dust, mist, or oil, while potentially problematic in their own right, do not describe the specific concern associated with worn wipers as clearly as chips do. Chips are a direct result of the machining process and are more likely to accumulate if wipers fail to perform adequately.
