Final answer:
CNC machines enhance productivity through precision, consistency, speed, and flexibility, leading to faster production times and reduced human intervention.
Step-by-step explanation:
The 4 features that CNC machines possess that allow increased productivity include precision, consistency, speed, and flexibility. CNC machines offer high-precision manufacturing, which means products are made with exact specifications every time, leading to greater product consistency. Their speed enables quicker production times compared to manual machining.
Flexibility in CNC machines allows for quick changeovers between different production jobs, reducing downtime and enhancing production schedules. Lastly, the automated nature of CNC machines reduces the need for human intervention, further increasing productivity.
