Screw and bolt seats at the right depth

    Countersinking & spotfacing

    Glintify identifies every countersink and spotface from the part's geometry. Countersink angle (90° standard, 100° for UNC, 120° for thin sheet) and diameter are read directly. Spotfaces for nut/washer seats are classified separately. Combo operations (drill + sink in one tool) are flagged as time-saving.

    // Detection

    What Glintify detects

    The system analyzes the part's geometry and extracts every manufacturing-relevant feature without manual input.

    Extracted data

    Countersink angle, diameter, depth, bottom plane, spot plane

    // Automation

    What is calculated automatically

    All measurements are extracted directly from the geometry.

    Number of countersinks per part
    Countersink angle (90°, 100°, 120°)
    Countersink diameter and depth
    Spotfacing (washer seat)
    Material and thickness from STEP
    // Quality

    Quality rules

    The system automatically checks whether the part fits within your capacity and flags designs that can cause production issues.

    Countersink depth > material thickness/2 → break-through risk
    Uneven edges → deburr before sinking
    Wrong angle (90° vs 100°) → screw head not flush

    Typical setup

    What a typical setup looks like for this operation.

    Tool choice by angle/diameter

    The same routing line as in Monitor

    On top of our time-based calculation, countersinking & spotfacing is also costed as a routing line ("beredningsrad") in Monitor's format: production group (work center), setup time, cycle time, allowance (F-time) and piece time, priced with the production group's cost factors. The line can be exported as an article with routing straight to your ERP system.

    Routing lineExplanation
    Production groupFetched from your ERP system or created from the machine park
    Setup timePer batch, not per piece — spread over the quantity
    Cycle timeThe technical time per piece, calculated from the geometry
    F-time %Allowance on top of the cycle time
    Piece timeCycle time × (1 + F-time %)
    Cost factorsMachine, wages + social charges and fixed manufacturing overhead in SEK/h, with a staffing factor
    Cost = setup time × rate + piece time × rate × quantity

    Markups for MO (material overhead), LO (subcontracting overhead), AFFO (general overhead) and profit are added at quote level — exactly as in Monitor's pre-calculation.
