- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
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.
Reduction or removal of workhardening effects, without motion of large-angle grain boundaries.
Discipline involving self-actuating and self-operating devices. Robots frequently imitate human capabilities, including the ability to manipulate physical objects while evaluating and reacting appropriately to various stimuli. See industrial robot; robot.
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.
Manufacturers struggling to get CNC machines to communicate directly with their collaborative robot now have a solution: VersaBuilt’s CNC Communication URCap is a simple yet powerful interface for machine tending applications with Universal Robots. The URCap allows a UR cobot to easily execute any machining program stored on the CNC directly through the cobot’s own teach pendant. Initially launching for Haas CNC machines, VersaBuilt will develop UR interfaces for other popular CNC makes later this year.
The Haas CNC Communication URCap will soon be available through the UR+ platform, a showroom of products all certified to integrate seamlessly with UR cobots. The URCap maintains all Haas safety interlock features and works with Haas, VersaBuilt, and other third-party automatic door openers.
“VersaBuilt is excited to partner with Universal Robots to provide machine shops with automation solutions designed for high mix CNC manufacturers,” says Albert Youngwerth, CEO of VersaBuilt Robotics, a company helping machine shops automate thousands of part numbers of all shapes and sizes in turning and milling applications.
Another testament to this mission is VersaBuilt’s patented MultiGrip workholding system, soon available through the UR+ platform. MultiGrip includes an automatic vise, machinable jaws and an end-of-arm tool for the UR robot. MultiGrip was developed to address the frustration experienced when working with traditional robot grippers and CNC vises. “We ended up asking ourselves: why can’t the robot and CNC use the same jaws?” explains Youngwerth. His team developed the unique workholding system that allows the robot and the CNC to share a set of MultiGrip machinable jaws for infeed, outfeed and CNC machining, resulting in reduced engineering costs, easier robot programming, faster setup time, and enhanced processing capabilities.
Regional sales director for Universal Robots’ Americas Division, Stuart Shepherd, emphasizes the importance of better integration tools for cobots and CNCs. “CNC machine tending is one of the most popular tasks to automate with collaborative robots,” he says. “But there’s still hurdles to overcome in achieving seamless integration. VersaBuilt’s two new products are important tools in addressing this. We’re excited to welcome them to the UR ecosystem and share their solutions with the ATX audience.”
Joining VersaBuilt in the UR+ pipeline is Visumatic’s VCM-3X.2 Collaborative Screw Driving Package delivering repeatable joining operations handled directly through the UR cobot’s teach pendant. The system communicates to a screw driver control that handles a wide range of different screw driving feeds and routines. The VCM is bundled with pre-programmed fault recovery logic and Visumatic’s field-proven power bit advance, bit position sensors and fastener delivery confirmation.
