Tips and Techniques for Using a Detail Gouge
Woodturning Tools, Techniques, and Projects Alan N. Leland Tips and Techniques for Using a Detail Gouge Roughing with a Spindle Gouge I prefer to rough out my spindles with a 1 1/4” roughing gouge or a ¾” roughing gouge. Roughing out can be accomplished with a detail gouge but it takes a bit longer and the finished cuts are not as smooth. Used properly a 1 ¼” roughing gouge can leave nearly the same finish as a skew. For roughing cuts: the cut is started approximately 2” in from the tail stock end and proceeds in multiple 2” increments cutting toward the tail stock until approximately 3” from the head stock end of the blank at which point the direction of cut is reversed toward the head stock these cuts are accomplished with the tool handle perpendicular to the blank and the end of the handle down at approximately a 45 degree angle to insure that when the cutting edge makes contact with the wood that the bevel is rubbing and the tool is not cutting until the handle is raised up to start the cut. Hold the tool firmly but not tight as in all turning the tool needs to be easily manipulated and this can not be done with a tight grip on the tool. The feet should be spread apart and the body should be free to move with the cut. To achieve the most control, the flute of the tool is sandwiched between the thumb and fingers of the left hand. The thumb is exerting pressure down toward the tool rest and is griping the flute against the fingers. -

Numerical Control (NC) Fundamentals
Lab Sheet for CNC Laboratory Department of Production Engineering and Metallurgy Prepared by: Dr. Laith Abdullah Mohammed Production Engineering – CNC Lab Lab Sheet Numerical Control (NC) Fundamentals What is Numerical Control (NC)? Form of programmable automation in which the processing equipment (e.g., machine tool) is controlled by coded instructions using numbers, letter and symbols - Numbers form a set of instructions (or NC program) designed for a particular part. - Allows new programs on same machined for different parts. - Most important function of an NC system is positioning (tool and/or work piece). When is it appropriate to use NC? 1. Parts from similar raw material, in variety of sizes, and/or complex geometries. 2. Low-to-medium part quantity production. 3. Similar processing operations & sequences among work pieces. 4. Frequent changeover of machine for different part numbers. 5. Meet tight tolerance requirements (compared to similar conventional machine tools). Advantages of NC over conventional systems: Flexibility with accuracy, repeatability, reduced scrap, high production rates, good quality. Reduced tooling costs. Easy machine adjustments. More operations per setup, less lead time, accommodate design change, reduced inventory. Rapid programming and program recall, less paperwork. Faster prototype production. Less-skilled operator, multi-work possible. Limitations of NC: · Relatively high initial cost of equipment. · Need for part programming. · Special maintenance requirements. · More costly breakdowns.

The annual symposium was again held in Waco, as it will be for the foreseeable future. The construction was a major hassle, and we ended up was beaucoup going on in Waco, so if I missed anything hosting a “room” that was bounded by curtains, but the or anyone, I apologize. demos were super and we all had a great time. Speaking of our room, the new A/V system worked flawlessly. We’ve got a lot coming up in the next few months, starting Thanks to Thomas Irven and all those who have helped with the September demo by Paula Haymond, who will with this system. We did get a new speaker recently, and talk to us about her techniques for surface decoration. I’m I’m hearing that it is a big improvement. If you don’t agree, sure you have joined me in awe of some of her recent let me know. work. In addition to giving us a meeting demo, Paula will be leading two small hands-on workshops on surface Our lead demonstrator in Room 3 was Molly Winton, a decoration. The first class is full, and I hear from George very sweet and talented lady. Her daughter Jean was with Kabacinski that there is one place left in the second her, and Jean even got to turn a pen! Now Molly has to class to be offered Oct 9 at George’s shop. -
Century American Machinery and Machine Tool Building
From Depression to Globalization: Reconfiguring 20th Century American Machinery and Machine Tool Building Philip Scranton, Rutgers University Prologue Practical Machinist: 06-14-2003, 11:51 AM Let's talk about Machine Tool Making. 1. The industry is Capital Intensive. A machine tool maker has a huge amount invested in plant and equipment. 2. The industry is Labor Intensive. Almost all the workers are highly skilled and not only that, each worker has to have significant experience working in the specific shop making that company's machines. 3. The Industry is cyclic. Some years there is a big backlog of orders. Some years, there is hardly anything for the skilled and valued workers to do. 4. The "Technical" competition is Brutal. As soon as a new machine design is fit for production, some competitor brings out a newer design with faster spindle speeds or faster motions or some other feature that he touts relentlessly in the trade publications. A Machine tool can be rendered obsolete by the time the first article is being crated up on a maker's loading dock. 5. The reverse of this can happen. A machine tool maker can devise a highly sophisticated design that just doesn't sell. Giddings and Lewis has had this happen to them several times and Davenport Machine had it happen with a servo-controlled, multi-spindle automatic bar machine. 6. During slow times, a machine tool manufacturer can be in competition with slightly used machine of his own manufacture. This is happening right now. None of the above points have anything to do with the government, and the best of the foreign competition suffers all of the above situations. -
