With which type of change will the Constant Path feature NOT be maintained?

• A. Changes to programmed speed
• B. Changes to motion type
• C. Changes to tool frame
• D. Changes to program order

Answer: (A)

The Constant Path feature maintains the programmed motion along a pre-defined trajectory, ensuring the tool follows a specific path regardless of changes made to other parameters. When programmed speed is changed, it affects how quickly the machine moves along the path, but it does not alter the path itself or the way the machine executes that path. Therefore, the integrity of the original path remains intact even if the speed varies. In contrast, other types of changes—such as changing the motion type or tool frame—can directly influence how the path is executed. Changing the motion type can modify the nature of the movements (e.g., switching from linear to circular), which could disrupt the original trajectory. Similarly, altering the tool frame might affect the coordinate system used, potentially leading to a different path being followed. Changes to the program order can also impact the sequence of operations, which may introduce variations to the motion being executed as a result of that reordering. Hence, changing programmed speed is the only adjustment that does not affect the path itself, allowing for the constant path to be maintained.
