Mastercam X has been designed to reduce programmer interaction and increase machining flexibility. It features a streamlined customizable interface. Specially designed to minimize user interaction while maximizing programming options, the interface is completely customizable and can be set to each person's specific preferences. The "smart" ribbon bar further boosts efficiency and maximizes workspace by appearing only when needed and displaying tools specific to the job at hand.

The software features a suite of programming tools, including the Pencil Offset Finishing tool path. This new surface machining technique extends the crisp cleanup of a pencil trace tool path across an entire part by automatically sectioning the part into logical machining areas.

Mastercam X also introduces Machine and Control Definition. These are virtual descriptions of the actual machine tool and control used to cut a part, allowing the company to automatically customize its interface based on a customer's CNC machine. This means that the software is aware of what the machine can and cannot do, helping ensure a correctly programmed part.
