Which of the following is a consequence of neglecting machine maintenance in milling?

Neglecting machine maintenance in milling directly leads to a shortened tool life. When machines are not maintained properly, issues such as misalignment, excessive wear, and inadequate lubrication can occur. These factors contribute to the tools becoming dull more quickly and less effective in cutting materials efficiently. Additionally, a poorly maintained machine may produce greater vibrations and strain during operations, which can further degrade the tool's sharpness and structural integrity.

While some may think that neglecting maintenance could somehow improve accuracy or increase uptime, the reality is that without regular maintenance, machines are prone to breakdowns and malfunctions, which ultimately result in increased downtime and decreased accuracy of machined parts. Similarly, operator safety can also be compromised when maintenance is overlooked, as worn-out or malfunctioning equipment can lead to hazardous conditions. Therefore, the consequence of neglecting machine maintenance that accurately stands out is indeed the shortened tool life.
