Types of Chip Formation During Machining
As every one knows, chips are formed during the machining of workpieces. The side of the chip in contact with the cutting tool is normally shiny, flat and smooth while the other side, which is the free workpiece surface, is jagged due to shear.
It is important to study the formation of chips during the machining process as the former affects the surface finish, cutting forces, temperature, tool life and dimensional tolerance. Understanding the chip formation during the machining process for the specific materials will allow us to determine the machining speeds, feed rates and depth of cuts for efficient machining and increased tool life in the specific actual machining operation. During the machining process, three basic types of chips are formed. They are discontinuous chips, continuous chips, and continuous chips with built-up edge.
Discontinuous chip formation normally occurs during machining of brittle work material. This type of chips also occus in machining operation with small rake angles on cutting tools, coarse machining feeds, low cutting speeds. Discontinuous chip formation results in poor workpiece surface finish.
During continuous chip formation, a continuous "ribbon" of metal flows up the chip-tool zone. This is considered to be the ideal condition for efficient cutting action.
Continuous chip with built-up edge formation is basically the same process as continuous chip formation, except that as the metal flows up the chip-tool zone, small particles of the metal begin to adhere or weld themselves to the edge of the cutting tool. As the particles continue to weld to the tool, it affects the cutting action of the tool.
This type of chip formation is common in machining of softer non-ferrous metals and low carbon steels. Common problems are the built-up edges breaking off and being embedded in the workpiece during machining, decrease in tool-life and final poor surface finish of the workpiece.
Studies on the built-up edges have shown that the chip material is welded, deformed and then deposited onto the rake face of the tool layer by layer. It is thus possible to observe the presence of built-up edges by studying the back face of the chip during the machining process. This is normally used in micro or ultra precision machining operation.
To reduce built-up edges, improve the lubrication conditions, use sharp tools and better surface finish tool and also apply ultrasonic vibration during the machining process.

Japanese Swiss Screw Machining Company Boosts CNC Machining Capacity
Ceriotec Corporation has announced that it will invest another US$1 million in new CNC Swiss screw machines in 2006 to increase its Swiss screw machining capacity and productivity.
Suwa, Nagano, Japan 27/Jan/2006 - To expand its production capacity and machining productivity, Ceriotec Corporation has announced that it will invest another US$1 million in new CNC swiss screw machines in 2006. The company has invested a total of US$5 million in CNC Swiss screw machines over the 5 previous years.
"We have gradually replaced our cam operated Swiss type screw machines with the latest CNC Swiss style screw machines. Besides allowing us to eliminate the need for cams and their added costs, these latest CNC Swiss screw machines make us more competitive as they increase efficiency by about 30% and allow us to respond rapidly to short production runs and rush order jobs," says Hiroaki Oguchi, President of Ceriotec Corporation.
Established in 1951, Ceriotec Corporation has been using swiss screw machines or swiss automatics to supply Japanese watch-making, IT electronics, consumer electronics, telecommunications and automotive industries with miniature complex profile turned parts from diameter 0.1mm for over 50 years.
Swiss screw machining is used to make small, slender, complex and precision components. In the swiss screw machine, the bar stock material is gripped tightly and advanced by the sliding headstock through a guide bushing to the machining section. The machining section consists of stationary tools which are applied to the emerging bar stock. As only the part of the bar to be machined is exposed from the guide bushing, there is minimum deflection which allows the turning of small accurate precision parts. If the part is longer and needs more grip support at the front end, a sub spindle can be applied to grip it to reduce deflection during cutting. Accurate and close toleranced parts are possible with tight toleranced guide bushings and finely ground bar stocks.
Says Mr Oguchi, "Originally designed by the Swiss to make miniature watch parts, Swiss style screw machines have become the machining solutions for many turned parts manufactured from difficult to machine alloys and exotic metals. Swiss screw machines excel in manufacturing a complex profile part in one turning operation, thus eliminating secondary processes and costs. We look forward to business enquiries through Suwa Precision Engineering, our marketing office in Singapore."
About Suwa Precision Engineering Pte Ltd: Suwa Precision Engineering Pte Ltd is the marketing office for a group of Japanese precision engineering parts manufacturers from Suwa in Nagano Prefecture, which is the home base of major corporations such as Seiko Epson and Nidec Sankyo. These manufacturers have more than 40 years each in manufacturing precision products and components such as stamping dies, precision metal stamping (deep draw and high speed), precision swiss turned components and miniature balls from diameter 0.1mm, precision gears and pcb in small footprint (1mm by 2.5mm).

To Engrave Or Not To Engrave
Engraving... what comes to mind is the permanence and the sense of personal ownership it gives to a precious stone, metal, or wood. It basically entails removing a portion from the exterior of a bare material by etching signs, insignias, or designs.
Engravers-to-be need to choose from 4 techniques: hand engraving, pantograph, Computer Numeric Control engraver and laser engraver.
Hand engraving is the oldest approach of engraving and the most expensive too. This is performed with the use of a chisel or a sharp tool carefully tapped into the material surface with differently weighed hammers. Each tap should be controlled for precision and accuracy of the over-all design.
For minute design details, the hand engraver has to use a magnifying glass or enlarging equipment to ensure that the design is followed to the minutest details.
Engraving by pantograph or the drag method is another old style that requires the use of a device (the pantograph or commonly called a tracing machine) to scrape the surface of a material with the use of a sharp stylus manually operated by the engraver.
The basic concept is tracing the letters or the design patterns from the design paper to the surface material using a sharp tool or the pantograph. The risk of this method is the uneven, probably unprecised way of etching the design or letters.
Since the stylus operator controls the writing, mistakes like those caused by shaky hands are not unlikely to occur. Pantograph engraving is faster than hand engraving.
Computer Numeric Control (CNC) engraving is a more precise method as it is computer-controlled. The letters or design are written in a uniform manner and use particular graphic software like that of cross-stitching.
The computer changes a design into numeric instructions which is then transmitted to an equipment which follows the commands for each movement This method is more sophisticated in that one can vary the fonts and the sizes of the patterns just with a few clicks of the mouse.
Laser engraving, on the other hand, uses a laser beam rather than a stylus or a sharp tool, to etch a design on a blank surface.
However, laser engraving utilizes computer software to convert the design into numeric instructions. Engraving using this method is more precise, fast, and clean. The downsides to this method are its being high-priced and selective material requirement.
Materials commonly used for engraving are stone, brass, aluminum, wood, and plastic.
Brass and aluminum plates are normally thin and engravers etch on them and later attach them to trophies, frames, and other surfaces. The metals' glossed coating is first removed to enable the etching tool to write on the surface beneath. However, this process scratches only the top portion of the material.
Deep engraving, on the other hand, requires digging deeper into the material. This is particularly used for permanent name plates and industrial molds.
Wood, as well as plactic, is other commonly used engravers' materials. Wood engraving is not as common as brass, aluminum or plastic engraving. Engraving tools (laser or stylus) marks the wood material and the cut area is filled with coloring material to provide contrast.
Engraving on plastic is done on thin layers of the material, usually differently colored. The stylus or laser cuts away the upper portion of the plastic thus showing the next colored layer. Shown together, the over-all appearance of the engraving is one of contrasting colors.
One has to decide which approach he is most comfortable with, considering the price of the equipment and tools to be used in creating one engraved piece of art.

Japanese Escomatic Machining House Seeks Sales Reps for Marketing in USA and Europe
Shibue Seimitsu has appointed Suwa Precision Engineering in Singapore as its international sales representative and seeks sales reps for USA and Europe.
Suwa, Nagano, Japan 8/Jan/2006 - To extend its marketing into international markets, Shibue Seimitsu Co., Ltd., a specialist in escomatic machining for over 50 years, has appointed Suwa Precision Engineering in Singapore as its sales representative for the overseas markets outside Japan and China.
Established in 1951, Shibue Seimitsu has specialized in escomatic machining of miniature (diameter 0.3 to 6mm) precision complex profile parts with tolerance of +-20 microns parts and burr-free finishes for the electronics and watch industries.
In escomatic machining, as the coil stock is fed through the machine, it is straightened, and then moved into bushings that are the same size as the stock. The bushings support allows the escomatic machine to hold a very tight concentricity for the length of the part. The continuously fed self-straightening coil stock reduces the turning needed to achieve the desired diameter, and also leads to less wasted material, less down-time for reloading and therefore lower cost.
"Escomatic machining has excellent repeatability throughout mass production. Our ISO9001 certified factory operates 24/7 to meet your production requirements with minimal workers. We focus on complex profile escomatic machining of part such as hinge components for cell phones and micro motor shafts, " says Toshiaki Shibue, President of Shibue Seimitsu.
Says Ken Yap, Director of Suwa Precision Engineering "We hope to help Shibue Seimitsu reach out to new customers and even appoint other sales representatives in the States and Europe."
