MDF Cutting Optimizer: Fit More Parts on Every Sheet

MDF is cheap per sheet and expensive per project. A wardrobe or kitchen carcass job can eat 6–10 sheets of 18 mm board, and every 5% of waste you save is money back in your pocket. A cutting optimizer is the fastest way to get those savings — here is how it works and what to watch out for.

Where MDF waste actually comes from

• Hand-planned layouts — parts placed in cutting order, not size order, leave scattered dead strips.
• Ignored kerf — 3 mm per cut adds up to a lost strip the width of a small shelf over a full sheet.
• Forgotten offcuts — last week's leftovers are exactly the size you need for drawer bottoms, but nobody tracks them.
• Trim on veneered boards — 10–15 mm per edge disappears before the first part is even cut.

What an optimizer changes

A sheet cutting optimizer sorts parts by area, places the largest first, and repeatedly splits free space into two rectangles after every placement. The result: typical utilization of 85–92% on mixed part lists, versus 75–80% for a careful hand layout and much less for a rushed one.

Offcut reuse: the hidden second saving

The calculator reports every offcut larger than 100×100 mm. Save those into your inventory and start the next job by entering them as stock sheets — many small parts (drawer bottoms, cleats, stretchers) can come entirely from boards you already paid for.

Try it with your next MDF job: the MDF-friendly cutting calculator accepts any custom sheet size, supports mm/cm/inches, and shows the layout before you commit to a single cut. Free for small projects; Pro (USD 5/month) adds unlimited parts and DXF export for CNC.
