A 144-inch bar with ten inches reserved for its end loss yields 61 parts at a 2.175-inch feed pitch: two inches finished length, 0.125 cutoff and 0.050 facing. Six bars produce 366 pieces. At $120 per bar, purchased stock is $1.97 per part before any scrap credit.

Whole parts per bar and bar-feeder load
Bar-end loss is reserved before dividing by pitch. Pitch includes one cutoff and total facing per finished part. This conservative model charges a cutoff for the last piece and gives no credit for reusable drops.
| Measure | Result |
|---|---|
| Feed pitch | 2.18 in |
| Parts/bar | 61 |
| Parts/load | 366 |
| Total unconverted length/bar | 11.33 in |
| Finished-length yield | 84.72% |
| Stock cost/part | $1.97 |
Measure feed pitch at the actual process
The bar advances by more than the shipped length. Include the cut-off blade width and all facing stock that disappears from each pitch. If the part is picked off and back-faced, add the stock consumed by both ends once. The model charges one cut-off per finished part, including the last one, which is a conservative planning convention. It assumes constant pitch throughout the bar and no rejected start-up pieces. A family of different lengths needs a separate cutting plan.
Reserve the real unusable bar end
Remnant depends on the machine, collet, guide bushing, bar feeder and how the last piece is gripped. Use a measured limit from that cell rather than a generic Swiss percentage. The tool removes the reserve first and rounds the remaining capacity down to complete parts. Total unconverted length includes both the reserved end and the fraction too short to make another pitch. It does not include cutoff and facing chips, which were already consumed inside the repeated pitches.
Translate yield into a release plan
Parts per load multiplies whole-piece yield by the number of loaded bars; it does not promise unattended hours. Tool life, inspection intervals, chip management and feeder reliability can stop the run sooner. To buy material for an order, divide required good pieces by the proven yield and round bars up, then add a deliberate allowance for process scrap if needed. Do not multiply the part’s finished weight by an assumed yield and expect the same answer as a whole-bar purchasing decision. Retain the yield sheet with the stock quote and update it when the process changes.
