Ein informatives und interessantes Sachbuch des Ehepaares Diamond, aus dem man sich auf alle Fälle einige nützliche Informationen holen kann. Gute Ansätze bezüglich größeren Rohkostanteil in der Ernährung wirft es für mich jedoch die Frage auf, ob dieses Buch nicht nur für den warmen Teil der Erde geschrieben wurde. In Florida kann man die These, ganzjährig hauptsächlich Rohkost zu essen, durchaus realisieren. In unseren kühleren Breiten kann ich mir dies im kalten Winter jedoch kaum vorstellen. Ohne erwärmende Lebensmittel bzw. gekochte Speisen würde die Körpertemperatur zu sehr gesenkt bei einem derart hohen Anteil an rohem Obst bzw. Gemüse. Trotzdem erhält dieses Buch von mir 4 Sterne für viele wirklich gute Ansätze !

I've been involved in metalworking in its various forms for the past 14 years. On this website, I share some of the really cool things that I've learned while working in all kinds of different shops.

If you’re making a very deep hole, it’s important to make sure that your flutes are long enough that the chips can escape. If the chips aren’t sliding easily up the flutes and out of the hole, you’ll have to either reduce your peck depth substantially or look into other solutions like thru-spindle coolant.

Heat buildup is another reason that you might want to reduce your Q value. If you have a massive, kinda sharp HSS jobber drill that doesn’t have the web thinned out, you might be getting a really hot tool tip. At that point, though, you might want to rethink your reasons for your tool selection. Big HSS jobber drills are pretty old school in CNCland.

The material is cold-rolled steel (CRS), and we’ll use a 1/4″ carbide drill in our vertical mill to punch in these holes. The drill doesn’t have thru-coolant. Keep in mind that carbide drills generally don’t need to be spotted if they’re entering a clean, flat surface. Since 2″ is pretty deep for a 1/4″ drill, G83 is the ideal canned cycle for this application.

Keep in mind that the shallower your peck depth, the longer it will take to drill the hole. This means that for low-volume production, you might not mind a few extra seconds per hole for the sake of playing it safe, but if you’re making thousands of holes….

The G83 milling canned cycle is one of the most common drilling cycles in use. In this quick article, I’m going to show you what it does, how to program it, and when to use it.

Again, nothing that you’ll notice in small quantities, but every millisecond adds up when you’re drilling thousands of holes.

Der Nachfolgeband der Gesundheitsfibel "Fit for Life", aber meines Erachtens unnötig. Viele Wiederholungen, nur wenig neue Informationen .... die Diamonds hätten es beim ersten Teil belassen sollen. Schade.

I've been working in manufacturing and repair for the past 14 years. My specialty is machining. I've managed a machine shop with multiaxis CNC machines for aerospace and medical prototyping and contract manufacturing. I also have done a lot of welding/fabrication, along with special processes. Now I run a consulting company to help others solve manufacturing problems.

For example, you shouldn’t have any major problems with drilling a 1/2″ hole in mild steel to a depth of 0.5″ without pecking. With a Q of 0.25″, though, the machine would peck once as it drills to that depth.

There are several canned cycles that are important to learn if you want to get the most out of your CNC machine. If you’re still learning the ropes, I’d highly recommend checking out my Beginner’s Guide to Canned Cycles for Milling.

Forge welding is essentially the oldest way of joining two pieces of metal together. Some say that it's been around for almost 4,000 years, starting from when people were learning to smelt iron from...

For example, Haas machines can use an I,J and K command to specify peck depth instead of the Q value. Check your programming manual to see if it’s available on your machine. Here’s what these commands mean:

At each hole, the drill will lift up and out of the hole at a set interval, pulling the chips away from the cut zone. This also allows coolant to get down to the tool tip if you’re not using thru-spindle coolant.

I really like using rebar for making all kinds of industrial-looking welding projects. It's also useful for things like reinforcing concrete, surprisingly. There are also a lot of different tools...

That means that for a 1/2″ diameter hole that’s 3″ deep, a peck depth of 0.25″ is about the most you’d probably want. To play it safe, I’d start with a Q value of 0.2.

With the IJK values, you can use an I value of .5 so that the drill won’t waste time pecking when it doesn’t need to. You could use a J value of .05″ and a K value of .25″ so that it will gradually reduce the depths of each peck. This overall will save you a little time on each hole.

- ein Buch, das ich in einem Hotelzimmer auffand und mich neugierig machte... das amerikanische Ehepaar Diamond legt hier seine Theorien rund ums Thema Verdauung, Lebensmittelkombination/ -verträglichkeit und -bestandteile dar, abschließend gibt es auch einen Rezeptteil. Vieles wird angesprochen, das der Buchtitel ausspart, z.B. scheint davon ausgegangen zu werden, dass ja eh jeder abnehmen will. Propagiert wird Trennkost, die Bezeichnung selbst fällt nie. Einige praktisch gute Ansätze sind sicher zu finden, obgleich es insgesamt wohl zu weiteren ernährungstechnischen Verwirrungen für alle nicht studierten ErnährungswissenschaftlerInnen unter uns führen dürfte. Abstoßend fand ich teils die Sprache und Argumentationsweise (oder ist nur die Übersetzung so schauderhaft schlecht?!) - übertriebene Beispiele, brüchige dafür aber dramatisch aufgebauschte Argumente und bildhafte Irritationen (z.B. man solle sich immer wenn man Milch trinken möchte vorstellen, am Euter einer Kuh zu hängen... !?!). Als Vegetarierin, Sportlerin und gewissenhafte Konsumentin fand ich vom gesundheitlichen Aspekt viel Bekanntes vor, einiges erscheint mir jedoch dramatisiert dargestellt und vor allem furchtbar formuliert.

However, if you’re machining something gummy or otherwise challenging, you might be best off decreasing that value to something like .15″ or even 0.1″.

All other things being equal, the drill diameter is generally what determines your Q value. At any depth greater than 4xD, you generally don’t want to exceed a peck of 0.5xD.
