Which key allows an operator to adjust the programmed feed rate in 1% increments on the Haas control?

• A. Speed control
• B. Feedrate override
• C. Handle control feedrate
• D. Jog control

Answer: (C)

The ability to adjust the programmed feed rate in 1% increments on a Haas control is primarily facilitated by the feedrate override feature. This feature allows an operator to fine-tune the speed at which the CNC machine operates without altering the actual program code, providing flexibility to adapt to different materials or cutting conditions. The feedrate override key can be used to increase or decrease the feed rate during machining, enabling the operator to respond dynamically to changes in the work environment or to enhance safety and machining efficiency. This capability is critical for optimizing operations, especially when dealing with tools and materials that may require adjustments to improve surface finish or extend tool life. The other options focus on different functions, such as jogging the machine or controlling spindle speed, which do not provide the specific functionality of adjusting the feed rate in increments as required by the question. This distinction clarifies why the feedrate override is the appropriate answer in this context.
