Final answer:
Fine particles from machining can lead to decreased tool life, poor surface finish, and increased risk of respiratory problems for workers.
Step-by-step explanation:
When fine particles form during machining, several issues can arise. These include decreased tool life, due to the abrasive nature of the particles that can wear down the cutting edges of the tools. A poor surface finish can also result from these particles adhering to the machined surface or causing irregularities during the cutting process. Furthermore, these fine particles pose an increased risk of respiratory problems for workers, as they may inhale these harmful particles, leading to conditions such as asthma, bronchitis, and other respiratory diseases. Thus, the health impacts along with the detriment to the machining process make for significant concerns in industrial environments.
