MY ERP - Cutting Optimizer

1D and 2D cutting optimizer integrated into the sales flow

Module functionalities

• Solver CP-SAT from Google OR-Tools
• Fallback FFD (First Fit Decreasing)
• Multiple stocks and lengths support
• Kerf management
• Ideal for bars, tubes and profiles
• Guillotine with recursive backtracking
• CP-SAT NoOverlap2D for feasibility
• rectpack MaxRects Best Area Fit
• Trims on edges and rotation of pieces
• Ideal for wood, glass and metal sheets
• Native OWL 2 widget on form
• Plans with labels and dimensions in cm
• OptiCutter style with pastel palette
• Patchwork areas with striped pattern
• View by consumed sheet/bar
• QWeb report with cutting plans
• One page per cut sheet/bar
• List of parts and dimensions
• "Cutting Optimizer" button on sale.order
• Apply results to order lines
• Automatically calculated stock quantities
• Cutting work line traceability
• Create manufacturing orders (mrp.production)
• One MO per stock product consumed
• Direct link with cutting work
• Consumption control from inventory
• Automatic capture of waste areas ≥ 5cm
• Create stock records as reusable scraps
• Reuse in future optimizations
• Traceability of source work
• Parameterizable 1D and 2D materials
• Default kerf, trim, grain and rotation
• Stocks linked to product.product
• Actual quantities from Odoo inventory
• Endpoint POST /api/v1/cutting/optimize
• Bearer Authentication with API Keys
• Stateless: parts and stocks via JSON
• Returns results with SVG plans
• User and Manager Groups
• Multi-company rules on jobs and stocks
• CUT/AAAA/00000 sequence
• Inherit Sales permissions
• Cascade of 2D solvers: Guillotine with Greedy CP-SAT rectpack NFDH backtracking. Automatically selects the best result.
• GCD Scaling: Reduces the domain of the solver by dividing dimensions by their GCD (e.g. 3270×2110 327×211), speeding up resolution times by 4-10×.
• Roll mode: Support for roll materials (infinite length in one dimension).
• Grain/grain: Respects the grain direction in wood or decorative grain.
• Piece rotation: Configurable by job (allows or prohibits rotating pieces 90°).
• Unlimited stock: Quantity -1 indicates infinite stock (consumable products or without link to inventory).
• Configurable time limit: Default 30 seconds, adjustable by job or globally.
• Create quote or sales order with products to be cut.
• Click the "Slice Optimizer" button in the OS.
• Define required pieces (length, width, quantity, label).
• Select available stocks (inventory or scraps).
• Run "Optimize" — the system calculates the cutting planes.
• Review SVG layouts and metrics (usage, waste, scraps).
• "Apply to Order" — updates sales order lines.
• "Create Production" — generates production orders.
• Print PDF report and deliver to the workshop.
• Draft: Defining parts and stocks.
• Optimized: Layouts calculated and ready to review.
• Applied: Results applied to the sales order.
• Canceled: Job discarded.
• After optimization, waste areas ≥ 5cm are recorded as stock with is_remnant=True.
• In future optimizations of the same material, the scraps are automatically included.
• When consumed, the patch is deactivated and traced to the job that used it.
• Own models: cutting.material, cutting.stock, cutting.piece, cutting.job, cutting.layout, cutting.layout.piece.
• Extends: sale.order, sale.order.line, mrp.production.
• Frontend in OWL 2: cutting_layout_viewer components and cutting_layout_field widget.
• Decoupled Odoo optimization engine (pure Python) — testable in isolation.
• QWeb PDF report with embedded SVG plans.
• Compatible with Odoo Enterprise and Community Edition.
• Depends on: base, mail, product, stock, sale_management, mrp.
• Messaging (mail)
• Product
• Inventory (stock)
• Sales (sale_management)
• Manufacturing (mrp)
• rectpack — required
• ortools — recommended (CP-SAT solver)
• Without ortools: module uses FFD and guillotine as fallback
