Holiday Trivets: A CNC Gift Idea

Nov 29, 2011   //   by Bob Warfield   //   Blog, CNC Projects, Cool  //  1 Comment

Nov 27, 2011   //   by   //   Blog, Software  //  No Comments

A conversation with Dan is what inspired me to write the 10 Tips for Minimizing Breakage of Micro-Mills article yesterday. Today I notice he has published a nice mention of G-Wizard on his blog. Dan has several machining-related sites including “The Hobbyist’s Machine Shop Blog” and “The Hobbyist’s Machine Shop” where I first came across…

Nov 27, 2011   //   by Bob Warfield   //   Blog, FeedsSpeeds, Techniques  //  No Comments

Speaking of Dan and the tips for minimizing micro-mill breakage, I decided to flesh out an entire chapter on micromachining for our feeds and speeds cookbook. In addition to a slight facelift on the aforementioned micro-cutter breakage information, I went back through my archives and fished out a bunch of additional material. Micro-Turner’s Cubes, anyone?…

10 Tips for Minimizing Breakage of Micro-Mills and Other Tiny Cutters

Nov 26, 2011   //   by Bob Warfield   //   Beginner, Blog, FeedsSpeeds, Software, Techniques  //  5 Comments

Over time certain questions and queries start to stand out, and one I hear a lot about is that machinists are breaking their delicate micro-mills and other tiny cutters too often, and they’d like some pointers on how to avoid it. First thing is first, you need to have proper feeds and speeds for these…

Turning on the “Bat Signal” just means activating the “new…

Ever wonder why CNC is so much more sensitive to cutting speed than manual machining?

Nov 22, 2011   //   by Bob Warfield   //   Beginner, Blog, FeedsSpeeds, Manual, Techniques  //  No Comments

It turns out to be a function of the capabilities of the machine and the machinist. Simply put, the CNC can do all sorts of things a manual Bridgeport never was in the running for. Learn more in my latest article about CNC Cutting Speeds.…

Climb vs Conventional Milling Chapter in the Feeds and Speeds Cookbook

Nov 10, 2011   //   by Bob Warfield   //   Beginner, Blog, FeedsSpeeds, Techniques  //  No Comments

Many machinists exclusively use one strategy–they always climb mill (CNC’ers) or the always conventional mill (Manual machinists). Putting aside the important issue of backlash (Climb milling is dangerous on machines with a lot of backlash), there are some real strategic considerations in choosing a milling strategy. You won’t always want to use just one. Most…
