Knife Performance Tips for Digital Cutting
Cut Angle: Balancing Durability and Precision
Larger Cut Angles result in increased over-cut, particularly noticeable in thicker substrates.
Material Thickness Amplifies Over-Cut, requiring compensation in toolpath design or offset calibration
High-Angle Blades Offer Greater Durability, making them suitable for abrasive or high-volume applications, though at the expense of fine detail fidelity.
Knife Design: Blade Geometry and Application Fit
Thinner Blades Yield Higher Precision, ideal for intricate contours and lightweight materials—but are prone to flexing and fracture under load.
Rigid Single-Edge Blades are recommended for dense or fibrous substrates, offering enhanced stability and cut integrity.
Oscillating-Only Blade Designs: Some single-edge blades are engineered exclusively for reciprocating motion; using them in drag systems may compromise performance or cause tool failure.
Drag Knives: Speed-Optimized for Clean Cuts
High-Speed Operation is typical across most drag knife configurations, with minimal loss in edge quality.
Ideal for Vinyl, Thin Films, and Soft Substrates, where continuous motion and low resistance allow for rapid throughput.
Oscillating Knives: Controlled Motion for Tougher Materials
Optimal Feed Rates Range from .06m/s - .25m/s (140-600in/min), depending on material density, cut complexity and style of blade tip.
Reduce Plunge Speed and Lift Angles when navigating tight angles/curves or cutting rigid substrates to prevent blade deflection or premature wear.
Recommended for Foamboard, Corrugated Plastics, and Composites, where reciprocating action enhances penetration and edge clarity.
