A rectangular width of 196 mm is covered by parallel straight cuts. The first cut covers 40 mm; each additional pass extends coverage by 25 mm. The programmed feed length per pass is the work length 280 mm plus 20 mm total approach/overrun. Use 350 mm/min. Count only these straight feed moves; return and indexing moves are excluded.
Calculate the additional passes after the first. Keep intermediate values unrounded; round the final answer to 4 decimal places if needed.
