Hot trends in cutting tools

Fast, flexible custom tooling, easy access to tool data through cloud technology and automation are some of the technologies driving tool production processes, according to a recent discussion between two industry executives.

ANCA North American president Russell Riddiford, who was attending an award ceremony at ARCH Cutting Tools in Latrobe, Pennsylvania, to celebrate the ARCH’s win in the 2020 ANCA Tool of the Year competition, sat down with ARCH Cutting Tools President Jeff Cederstrom to look at industry trends. The talk examined the collaboration between both companies, future cutting tool trends and how best to maximize the opportunities of these trends.

Offline and in-process solutions

Cederstrom identified the growing trend towards custom tooling. While he described ARCH as a “full-service, one-stop shop with a broad portfolio of standard tools,” he acknowledged that the company sets itself apart in the market, thanks to the breadth of their custom tooling capabilities. Many customers work with ARCH Cutting Tools, looking for custom solutions to reduce their manufacturing costs. This leads to combination tools with complex geometries. Cederstrom said the combination of skilled machinists, designers and technology that ANCA provides enables the process to flourish.

Recognizing the market need for adaptability to produce custom tools Riddiford highlighted the range of processes offered by ANCA that are targeted to increasing the “speed to get to the grinding point.” ANCA’s 3D simulation software generates a special profile offline, while the machine is still running and completing the previous jobs. The program is then downloaded to the machine, allowing ARCH to obtain better production of the first tool.

ANCA offers ARCH the option to inspect its tool on the machine, using the LaserPlus System. The system measures the profile tool, automatically compensating the machine to correct any errors in geometry. Another option is to take the tool to a Zoller presetter, as Zoller is integrated with the ANCA machines on the floor. A full contour scan is performed using the Zoller »genius3« to identify any imperfections in the tool.

Riddiford said he sees the importance of having the “first tool right” as a critical point for production. After the pre-grind process through simulation to perfect the tool before it even gets to the machine, ANCA offers customers maximum accuracy, surface finish and stability throughout the grinding process. He added that ANCA is the as the only company with a full linear motor product line. Another new technology is spindle temperature control, a software function that maintains consistent spindle temperature. Providing this stability again allows the first tool in production to be right.

ARCH Cutting Tool’s winning tool offers five separate functions demonstrating the kind of complexity that is in demand. Cederstrom commented that custom tooling is becoming more challenging and ANCA’s solutions offer significant benefits. “Having the software so that it is user-friendly, and we can adapt to a request quickly and having not only the software but the machining technology to support it … is critical to us,” he said.

Cederstrom’s company recently launched a program called “Hot Shop” to showcase their speed from production to delivery. If a customer needs a custom tool quickly, ARCH can produce any geometry of a solid carbide round tool and have it delivered within one week. Cederstrom explained: “Having equipment that is nimble and fast on the floor enables (this speed)”.

Connected machines and integrated automation

ARCH has developed a web portal called “ARCH Specials.” Customers can download drawings, a DFX file or use pulldown menus on the company Website, or talk to engineers to generate a fast RFQ for application specific custom tools.

Online capabilities and cloud technology are also a growing trend. ANCA can network all machines through their Management Suite software, which allows users to replicate and download files from anywhere in the country, such as across ARCH’s multiple facilities. Additionally, users can monitor real-time performance of their machines to schedule and maintain the machines, as well as predict maintenance requirements to minimize downtime.

Both Cederstrom and Riddiford identified automation as another rising trend. From customers looking for more output, better quality and more productivity, to the social distancing requirements of COVID, to the gap in skilled labor; increased automation provides a solution to these challenges. To this end ANCA has developed AIMS (ANCA Integrated Manufacturing System), said Riddiford. “This is the ability to bring a stock piece of carbide at the front end and at the back end have a finished tool…without manual or operator input throughout the process. This allows end-to-end grinding.” Adding to ANCA’s product range is automated laser etching with the AutoMarkX, which fits with AIMS to complete the process.  Riddiford added: “Some people might think of it as the future, but AIMS is here today.”

  • grinding

    grinding

    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

  • linear motor

    linear motor

    Functionally the same as a rotary motor in a machine tool, a linear motor can be thought of as a standard permanent-magnet, rotary-style motor slit axially to the center and then peeled back and laid flat. The major advantage of using a linear motor to drive the axis motion is that it eliminates the inefficiency and mechanical variance caused by the ballscrew assembly system used in most CNC machines.

  • web

    web

    On a rotating tool, the portion of the tool body that joins the lands. Web is thicker at the shank end, relative to the point end, providing maximum torsional strength.
