ProfitTurning High-Speed Lathe Roughing Strategy

ProfitTurning is a high-speed lathe roughing strategy developed by DP Technology Corp. for OD/ID/face cutting and other tasks. Fast, secure and efficient, it also extends tool life by significantly minimizing wear. Compared to conventional ramping methods, ProfitTurning reduces machine cycle time as well as the frequency tooling inserts need to be replaced.

DP Technology’s R&D Director of Product and Engineering Ivan Kristic reveals the science behind ProfitTurning’s performance: “ESPRIT 2016’s ProfitTurning toolpath maintains consistent cutting forces and chip loads, allowing cutting speeds to be significantly increased. By employing trochoidal turning and controlled engagement techniques,
the ProfitTurning toolpath also reduces vibration and residual stresses, which in turn makes it particularly well-suited to thin walls or hard materials, especially superalloys. The net result is significantly reduced cycle times and maximized productivity.”

ESPRIT 2016 uses a physics-based cutting engine which provides the foundation for the technologies such as ProfitTurning. While traditional cutting strategies consider only the geometry of materials, ESPRIT 2016 taps deeper into the science of how different industrial materials can be cut in the most efficient ways possible. Its new toolpath technology uses the principles of physics to formulate unique strategies for each cutting challenge.

To do that, ESPRIT 2016 inputs all relevant factors in the toolpath algorithm such as tool material, tool shape, workpiece material, tool speed, feed rate, chip deforming, chip load, machine tool power, acceleration and deceleration. This helps establish complete control of the cutting environment, allowing for optimal cutting everywhere along the toolpath.

  • feed

    feed

    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • lathe

    lathe

    Turning machine capable of sawing, milling, grinding, gear-cutting, drilling, reaming, boring, threading, facing, chamfering, grooving, knurling, spinning, parting, necking, taper-cutting, and cam- and eccentric-cutting, as well as step- and straight-turning. Comes in a variety of forms, ranging from manual to semiautomatic to fully automatic, with major types being engine lathes, turning and contouring lathes, turret lathes and numerical-control lathes. The engine lathe consists of a headstock and spindle, tailstock, bed, carriage (complete with apron) and cross slides. Features include gear- (speed) and feed-selector levers, toolpost, compound rest, lead screw and reversing lead screw, threading dial and rapid-traverse lever. Special lathe types include through-the-spindle, camshaft and crankshaft, brake drum and rotor, spinning and gun-barrel machines. Toolroom and bench lathes are used for precision work; the former for tool-and-die work and similar tasks, the latter for small workpieces (instruments, watches), normally without a power feed. Models are typically designated according to their “swing,” or the largest-diameter workpiece that can be rotated; bed length, or the distance between centers; and horsepower generated. See turning machine.

  • superalloys

    superalloys

    Tough, difficult-to-machine alloys; includes Hastelloy, Inconel and Monel. Many are nickel-base metals.

  • toolpath( cutter path)

    toolpath( cutter path)

    2-D or 3-D path generated by program code or a CAM system and followed by tool when machining a part.

  • turning

    turning

    Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
