Hands Free: Turning Performance
Shop owners who operate multitask machines talk about the time and cost benefits of producing parts in a single chucking. They also discuss some of the problems they had when adopting the technology. Accompanying Articles focus on a multitask users group and machine that hard-turns and grinds.
Size Matters
The trend toward developing finer and finer carbide grains continues. The author looks at recent developments in the production of nanosized tungsten-carbide grains, which are smaller than 0.2 microns in diameter. Though not used widely at present for the production of cutting tools, some predict that will change as the technology evolves.
Killing Time: Drilling Performance
One company instituted a comprehensive plan for reducing setup times and saw its average setup time drop from 252 minutes to 39 minutes. The plan involves everything from standardizing tooling to consolidating raw materials to creating families of parts. The author outlines a step-by-step program that readers can apply to their metalworking setup operations.
Double Header
The author discusses the advantages and proper application of twin-cutter boring tools. They're recommended for rough-boring applications on castings, forgings and other jobs requiring a tool that can bore a cored hole. Details are provided on the three basic types of methods for rough boring with a twin cutter: balanced, stepped and full profile.
Tool Men
Establishing a good relationship with your cutting tool salesperson can benefit your operation. A good salesperson can help solve problems you don't have time to tackle and offer recommendations for machining difficult parts. The author also addresses what to do when a relationship sours.
Talking Points: Industry Trends & Analysis
A conversation with Lee Iacocca, chief spokesman and a member of the board of directors of The Online Asset Exchange (onlineassetexchange.com), a service for buyers and sellers of machine tools. Iacocca also is involved with a company that produces electric bicycles. The former president of Ford Motor Co. and of Chrysler Corp. was at WESTEC 2000, where he met with CUTTING TOOL ENGINEERING to discuss manufacturing's role in the economy, his perceptions of the machine tool industry and business-to-business e-commerce.
Back to Basics: Drilling Performance
Gundrilling: going deep
Smoother Roughing
The author discusses the disadvantages of using a finishing endmill for roughing applications. He also presents a quick, systematic, step-by-step series of calculations that allows machinists to optimize metalcutting when applying coarse-pitch, cobalt-HSS roughing endmills.
From Maudsley to CNC: The Evolution of Thread Cutting
A look at the different types of inserts used for single-point threading and how to figure feed rates for cutting threads on a CNC lathe. Also offers programming tips and recommendations for reducing tool wear.
Abrasive Personality: Drilling Performance
High-silicon aluminum--aluminum that consists of at least 11.8 percent silicon--has qualities such as lightness and strength that appeal to automakers. The abrasives nature of the material, however, makes it difficult to machine. The author offers suggestions for milling, tapping, drilling, turning and grinding high-silicon aluminum.
Getting to the Bottom of Chatter
Tool chatter is one of the biggest obstacles to effective machining that job nshops face. The author discusses the sources of chatter and offers nsuggestions for minimizing it.
Added Dimensions: 5-Axis Machining
A rotary table allows a 3-axis vertical machining center to machine in the n4th and 5th axes. The author explains the different types of rotary tables nthat are available and discusses the advantages and disadvantages of each.
