In the debut episode of The CNC Chef, Bob Warfield from CNCCookbook.com cautions against slowing down your feed rate to avoid tool rubbing. A new monthly video series from Cutting Tool Engineering, The CNC Chef will address a variety of machining challenges in the coming months, including:
- Tool deflection
- Micromachining
- The role of coolant
- Deep hole drilling
- Tapping tricks and techniques
About The CNC Chef Video Series: Bob Warfield founded CNCCookbook.com and built it up to be one of the most popular CNC Blogs on the Internet. Thanks to his work with CNCCookbook and the G-Wizard software series, Warfield routinely receives questions from shops all over the world.

- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- feed
feed
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
- tapping
tapping
Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
