Measure the completed job

Material feed rate describes how quickly fabric moves through a machine. Accepted finished output describes how much usable work reaches an agreed completion point. They answer different questions. For a production trial, observe the complete job cycle so loading and handling time remain visible alongside cutting time.

Use a simple rate: accepted finished quantity / agreed elapsed time. Match the units explicitly, such as accepted bundles per elapsed hour or accepted rolls per elapsed hour. Record the quantity and elapsed time as well as the calculated rate.

Agree on the clock

Before the trial, agree when timing starts and stops. Include loading, fabric alignment, job setup, changeovers, and normal collection within the observation window whenever these belong to the work being evaluated. If a task happens before timing begins, state that clearly.

Record interruptions and explain how they affect the reported window. Do not remove ordinary waiting or handling simply because the machine is not cutting. The result should describe the observation conditions readers can reproduce.

Define accepted output

Agree on the finished unit and acceptance checks before counting. State what makes an item rejected, whether rework is needed, and whether reworked items become accepted before the trial ends. Keep rejected and unfinished quantities visible rather than counting everything that leaves the machine as finished output.

For a YC-1700 strip-cutting job, agree whether output is counted as individual accepted strips or as a defined collected quantity. For a YC-1700E cutting-and-rolling job, the agreed unit may be a completed roll. Define the contents and completion point; different output units are not equivalent, and collection or packing steps must be confirmed separately.

Match the trial to the order mix

A repeat-order trial can show a workflow with stable material and settings. A mixed-order trial should include the relevant material, size, or job changes and the associated alignment and setup time.

Describe which context was observed. A brief run with uninterrupted feeding cannot establish accepted output for a full shift. Discuss longer-period expectations only with additional evidence about the actual schedule, order mix, and interruptions.

Keep a useful trial record

Capture enough detail to interpret the result:

  • Material and job description, including the order mix.
  • Agreed start, stop, finished unit, and acceptance checks.
  • Accepted, rejected, reworked, and unfinished quantities.
  • Loading, alignment, setup, changeover, and collection activities observed.
  • Elapsed time, interruptions, and any work completed outside the window.

When requesting a trial from Yuancheng Machinery, ask to agree on these observation conditions before comparing output.
