Keeping Accuracy Within Reach
Part quality is at risk if a machining center cannot hold tolerances at the farthest reaches of its work envelope. This makes volumetric accuracy a key indicator of a machine's performance. One machine tool builder discusses the implications.

Running EDM Economically
Many shops are taking a closer look at the cost of operating a machine tool. How much energy does it consume? Does it create excessive heat, making the shop air conditioning work harder? Does it stretch the life of cutting tools and consumables?

CAD Input For EDM
This software runs on the wire and ram (die sinking) versions of the company's "LQ" Windows XP-based control unit. The software provides a special interface that allows the user to input 3D solid model geometry directly from the CAD system to use as input to the EDM control unit. Using CAD data as direct machine tool input has long been a dream that developers of other types of machine tools are now closing in on.

Turning Ideas Into Parts
To get maximum leverage from its manufacturing know-how, Krieger Machine, a CNC shop in Stuart, Florida, draws on all of its software resources - CAD, CAM and shopfloor programming. The shop relies on KeyCreator from Kubotek as its main CAD resource. Mastercam from CNC Software is its main CAM resource. On the shop floor, conversational programming on the Hurco vertical machining centers proves to be another vital resource. All three systems help the shop succeed as a reliable producer of precision parts for a variety of industries.

High Speed Wire Cutting Needs High Efficiency Filtration
High speed cutting with wire electrical discharge machining produces debris in the dielectric at a high rate. Without effective filtration, a wire machine quickly loses its ability to maintain high cutting speed, achieve the desired surface finish and obtain expected dimensional accuracy. Charmilles' approach to solving this problem has been to develop a filtration system that doubles the number of filter cartridges, from two to four.
