CNC Programming Handbook, Third Edition (Hardcover)

Product Description

Over its first two editions, this best-selling book has become the de facto standard for training and reference material at all levels of CNC programming. Used in hundreds of educational institutions around the world as the primary text for CNC courses, and used daily by many in-field CNC programmers and machine operators, this book literally defines CNC programming. Written with careful attention to detail, there are no compromises. Many of the changes in this new Third Edition are the direct result of comments and suggestions received from many CNC professionals in the field. This extraordinarily comprehensive work continues to be packed with over one thousand illustrations, tables, formulas, tips, shortcuts, and practical examples.

The enclosed CD-ROM now contains a fully functional 15-day shareware version of CNC tool path editor/simulator, NCPlot(tm). This powerful, easy-to-learn software includes an amazing array of features, many not found in competitive products. NCPlot offers an unmatched combination of simplicity of use and richness of features. Support for many advanced control options is standard, including a macro interpreter that simulates Fanuc and similar macro programs.

The CD-ROM also offers many training exercises based on individual chapters, along with solutions and detailed explanations. Special programming and machining examples are provided as well, in form of complete machine files, useful as actual programming resources. Virtually all files use Adobe PDF format and are set to high resolution printing.

New and Updated Features of the 3rd Edition
- Detailed section on CNC lathes with live tooling, including examples - Image files of many actual parts, used as examples - More programming examples (both in printed text and on the CD-ROM) - Optimized for the latest Fanuc and related control systems - Additional formulas, calculations and handy reference material - Fourth axis programming (indexing and rotary) - Improved index for better search of topics

CNC Programming Circular Interpolation (Helical Motion)

Content Inside :

CNC programming tutorial Circular Interpolation (Helical Motion) Circular Interpolation • G02, G03, I, J & K – G02: Circular interpolation (CW) – G03: Circular interpolation (CCW) – I, J & K (Use when <=360 degree) • Incremental distance from SP to CP of arc – I: Specifies the incremental ±X distance from the center of the tool at the start of the arc to the center of the arc. – J: Specifies the incremental ±Y distance from the center of tool at the start of the arc to the center of the arc. Why I, J & K instead of just R? • R is easier to define, easier to make a mistake and get an incorrect radius. • With R, the machine still do the work whether the R is correct or incorrect. • With incorrect I, J & K, the machine will stop and gives an error message before executing. • With R, to generate a circle path of over 180 degrees, then specify a negative R. Sample program (R and J).

This is what a miter saw ought to be: accurate, sturdy, powerful, versatile, user-friendly and packed full of cool features.

If we had to choose a favorite aspect, it would have to be the handle. It’s vertical. It’s horizontal. And it’s a couple of other things in between. It locks quickly and easily into any of four positions, so both lefties and righties have complete comfort and control.

This saw is beefy -- it weighs in at 55 pounds and it’s got a nice, wide footprint that promises the ultimate stability, and sliding extensions bring your support area to 37-1/4 inches. If you’re in the market for a stand for this saw as well, we like both the Bosch TracRac as well as the DeWalt DW723.

The dual bevel is a great feature, swinging 47 degrees left and 46 degrees right, with positive bevel stops at 31.6 and 33.9 degrees for flawless crown molding cuts. For miter cuts, the blade swings an impressive 52 degrees left and 60 degrees to the right. There’s even a micro-fine adjustment here, letting you override a detent by as much as 2 degrees. Now that’s precision.

We absolutely love the fence on this saw – Bosch calls it a Speed-track sliding fence – because it’s a full 4 inches tall and has a beautifully readable inch-scale on it. It’s perfect for crown molding, handling pieces up to 6 inches wide when angled against the fence.

We’re suddenly rethinking our earlier statement about our favorite feature on this saw; on second thought, it might well be that all the controls – including the bevel lever – are up front. We’re pretty tired of reaching around a saw body to set a bevel, so this is a most welcome upgrade. Adjustments are so much faster and easier, and all the scales are right up front, too.

Capacities are generous, thanks to the slide, with a max cut of a 2-by-12 at a 45-degree bevel and 3-5/8 by 12 inches when the blade is upright.

And yes, this saw has a laser cutting guide, but unless you really want one, we wouldn’t let that sway a decision on this saw one way or the other. It’s a nice feature if you’re likely to use it, but most of us woodworkers prefer to get a visual on exactly where that blade meets the wood.

In all, this is a beauty of a saw, with features you aren’t going to find on other saws in its class. And we still can’t pick our favorite between the handle and the up-front controls. It’s all good. -- Kris Jensen-Van Heste

Product Description

Amazon.com Product Review
A benchtop router offers significant advantages over a handheld machine. It's safer, because you're moving the wood over the bit instead of the other way around. It's also versatile, allowing you to do a number of cuts that aren't possible with a handheld. And because it has a fence, it gives you a degree of control and precision that is simply impossible with freehand routing.

Because you're sliding the wood across the surface of a bench router, it's important that the surface be as frictionless as possible. The RA1181 features a generous 27-inch long by 18-inch wide table that's made out of slick but durable cast aluminum. In addition, he surface near the fence is rough-ground to minimize surface contact, which further reduces friction.

Though the caveat "some assembly required" applies here, the manual is clearly written, and I found the setup process to be straightforward. Once fully assembled, the RA1181 attaches to just about any workbench via the leg assemblies, which have flat "feet" that you can clamp to the table. You can also use the pre-drilled holes to screw it to your work surface if you don't need it to be portable. (Note that most benchtop routers need to be mounted on a smaller table-using a standard worktable may leave it uncomfortably high.)

Once secured to the table, the RA1181 is very stable, and can handle high-horsepower routers and larger work pieces without bucking. The cast aluminum mounting plate accepts a variety of routers-and not just those made by Bosch. The fence is good and rigid, and is adjustable from 0 to 3-3/4-inches wide.

This is a great little machine, and its portability and capacity for bigger jobs makes it as good a fit on the job site as it is in the home workshop.--Josh Dettweiler

It’s a funny thing about jigsaws; most of us tend to reach for another tool in its stead, having had less-than-great experiences with the little beasts.

But here comes Bosch’s 1590, and it elevates the outcast jigsaw to the most-wanted list.

The first thing we liked about this saw is its heft; it’s beefy, solid and made with that famous Swiss quality. You wrap your hand around the soft, substantial grip, squeeze the ample trigger and the soft-start whirs gently; with hardly any effort from you, the blade slices through whatever’s ahead of it. Perhaps because it’s heavier than most jigsaws, there’s practically zero vibration, giving you a delightfully smooth, no-buzz experience, something pretty much unheard of in your average jigsaw.

Another nice feature is the speed mechanism: Set your maximum speed on the trigger dial, then control your speed up to that max by squeezing the trigger. On long cuts, you can lock the trigger on, too, and the blower actually does keep your cutline clear.

If that’s all this saw had going for it, that would be enough for us. But coolest of all is the blade-change system that literally ejects the blade in a split second, takes the new one and gets you right back to your cutting – all tool-free. Amazing.

If you’ve relegated the jigsaw to the bottom of your toolbox, you owe it to yourself to give this one a chance. We think it’s fantastic. --Kris Jensen-Van Heste
