CNC demo: multiple parts in one cycle
WayKen Rapid Manufacturing posted a video showing a single CNC cycle machining multiple parts at once to cut labour and idle time. The demonstration illustrates a takt‑aware setup that reduces operator interventions and machine changeover losses (x.com).
Computer numerical control, or computer-run cutting machines, usually make one part per setup; WayKen showed a fixture that lets one cycle cut several parts before an operator steps back in. (waykenrm.com) WayKen Rapid Manufacturing published the demonstration on X, formerly Twitter, in a post linked to card readers, and the company’s own materials say it runs an in-house machine shop in Shenzhen, China, with CNC machining offered from 1 to 10,000 pieces on demand. (waykenrm.com) The basic idea is workholding: clamp several blanks on one fixture so the spindle repeats the same toolpath across each position, instead of stopping after every single part. Haas Tooling describes tombstones and pallet fixtures as a way to machine multiple parts in a single setup and to load one block while another is running. (haastooling.com) WayKen markets the same logic in its own process videos. Its CNC page says five-axis machining can process up to five sides in one setup, which the company says reduces setups and cycle times while improving machine utilization. (waykenrm.com; youtube.com) “Takt time” is the production beat set by demand, not the machine’s top speed. Lean Enterprise Institute defines it as available production time divided by customer demand, which is why shops try to keep the spindle cutting instead of waiting through repeated loading and changeovers. (lean.org) That is where multi-part cycles fit. Lean Enterprise Institute says Single Minute Exchange of Die, the classic setup-reduction method, separates work that must happen while a machine is stopped from work that can be prepared while it is still running. (lean.org) In a machining cell, that can mean moving labor from “open door, swap one part, restart” to “load a larger batch, let the machine run longer, inspect at planned intervals.” Haas says additional tombstones can let shops load and unload parts on one block while machining parts on another. (haascnc.com) The tradeoff is flexibility. A fixture built for four or eight identical parts can lift throughput on repeat jobs, but it also ties up more material and demands tighter planning if the order mix changes mid-run; WayKen’s own videos frame the approach as batch-efficiency work, not a universal setup for every job. (youtube.com; waykenrm.com) WayKen’s demo lands in a corner of manufacturing where the gains are often less about faster cutting and more about fewer interruptions. The machine still removes metal the same way; the difference is how many finished parts come off before the next human touch. (waykenrm.com; lean.org)
