Cutting plans for steel bars
Place your required lengths in 6000, 6300, 6500, 6650, 7000 mm or custom stock. Review bar count, saw loss, remaining lengths and repeated cutting patterns.
Create a cutting pattern
Enter stock length, saw kerf, and each required length and quantity. The tool aims to reduce stock count; it attempts an exact search for suitable small or medium lists and otherwise uses deterministic placement.
Calculation model: for n pieces in one stock length, only (n − 1) × kerf between pieces is counted. The cut separating the last piece from a remnant, end trimming and clamping allowance are excluded. A single-piece bar therefore shows zero saw loss. Remaining length may be reusable; it is not automatically scrap. Plan additional actual cuts separately. A heuristic result carries no mathematical optimum guarantee.
This tool supports production planning. Check actual stock length, clamping, end trimming, surface defects and saw technology on the shop floor. Suggested stock lengths are input options, not availability promises.
Check the model with simple examples
Custom stock 2003 mm, two pieces of 1000 mm, kerf 3 mm: one stock length, 2000 mm of parts, 3 mm saw loss and 0 mm remaining. With kerf 4 mm these two pieces no longer fit together.
Stock 1500 mm, one piece of 1000 mm, kerf 3 mm: the model reports 0 mm between-piece saw loss and 500 mm remaining. This is not a statement that the physical separation cut consumes no material.
Read the result correctly
Saw loss and remaining length are reported separately. “Outside finished cuts” is their sum; it is not all irrecoverable waste. Repeated patterns state how many stock lengths use each recipe. A successful plan must include every requested length and quantity without exceeding stock length. Limits: 100 different rows and 1000 pieces per plan.
