CNCCookbooks Inc. says it invested a lot of time and effort into its "Complete Guide to CNC Mill Feeds and Speeds." It is one of a number of in-depth cookbooks the company offers to help you become a better CNC’er, and it was the first one it created.
The company has updated the guide to make it easier to navigate and find what you’re looking for. It also did some overhauling to improve readability in some places.
The guide is not just about feeds and speeds–it serves as our guide to all things cutter-related, so there are articles there on everything from materials to specific cutters to coolant issues.
Here are some of the new changes:
- New guides for cutter types, including cutter specific guides for single-flute endmills, ballnose cutters, taps, twist drills, fly cutters, slitting saws, and a whole host of other cutter specific articles.
- New guides by material. This is a work in process, and there a lot more articles to do here, but guides with tips and techniques for specific materials are being added.
- New page template for improved readability of these guide pages. A lot of work remains to integrate this template throughout all the guides, but the plan is to go through every article revising and updating it to make them all the most complete and up-to-date information you can find anywhere on CNC feeds and speeds.
Related Glossary Terms
- 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.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- milling machine ( mill)
milling machine ( mill)
Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
