Beyond the educated guess: General Industry Coverage
Planning is critical when operating CNC machines. When I began machining, CNCs were just coming into mainstream use. The first shops I worked in had only conventional (manual) machines. It wasn't until the mid-1980s that I started to notice the incredible versatility of CNC machines. The complex contours and shapes the machines could generate made many jobs much easier. The use of templates to file and sweep in surfaces was rapidly becoming a thing of the past.
