Learn blisk machining strategies at June 7 tech day

Emuge-Franken USA, Grob Systems Inc. and Concepts NREC are holding a complimentary Tech Day on June 7 from 10 a.m. to 1 p.m. Eastern time at the Emuge Technology Center in West Boylston, Massachusetts.

Attendees will learn milling strategies for blisk manufacturing and see live machining demonstrations on a GROB G550a 5-Axis machining center featuring EMUGE Circle Segment milling tools with programming from Concepts NREC MAX-PAC CAM software for turbomachinery applications.

Manufacturing professionals are welcome and encouraged to attend by registering here.

Technology experts will present and demonstrate key advanced strategies for highly productive blisk machining including:• Reducing finishing time with EMUGE Circle Segment (a.k.a. conical barrel) cutters in tandem with powerful MAX-PAC CAM strategies. Circle Segment end mills vastly reduce finishing times on parts featuring challenging geometric contours such as blisks. • High-speed roughing solutions using MAX-PAC's UPASS trochoidal strategy.• Improving accuracy and reducing chatter by utilizing a multi-depth mixed milling strategy.• Eliminating witness lines on the blade by utilizing MAX-PAC's finishing blending strategies.• High accuracy and maximum stability with the GROB G550a 5-Axis machining center which features a unique machine concept including a horizontal spindle position that permits the longest possible Z-travel path and optimum chip fall management. The arrangement of three linear axes offers maximum stability by minimizing the distance between the guides and the machining point (TCP). Three linear and two rotary axes permit 5-sided machining, as well as 5-axis simultaneous interpolation, with a swivel range of 230 degrees in the A-axis and 360 degrees in the B-axis.

Condition of vibration involving the machine, workpiece and cutting tool. Once this condition arises, it is often self-sustaining until the problem is corrected. Chatter can be identified when lines or grooves appear at regular intervals in the workpiece. These lines or grooves are caused by the teeth of the cutter as they vibrate in and out of the workpiece and their spacing depends on the frequency of vibration.

Use of computers to control machining and manufacturing processes.

Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.

Process of generating a sufficient number of positioning commands for the servomotors driving the machine tool so the path of the tool closely approximates the ideal path. See CNC, computer numerical control; NC, numerical control.

CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.

Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or "up" into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or "down" into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
