Struct ProcessWindowOptimizer 

pub struct ProcessWindowOptimizer {
    pub power_min: f64,
    pub power_max: f64,
    pub speed_min: f64,
    pub speed_max: f64,
    pub layer_thickness: f64,
    pub hatch_spacing: f64,
    pub e_low: f64,
    pub e_high: f64,
}

Scan-speed vs laser-power optimiser for minimal porosity and good surface.

Sweeps a discrete grid of (power, speed) pairs and scores each point using a combined porosity-and-surface-roughness cost function.

Fields

power_min: f64

Minimum laser power to evaluate (W).

power_max: f64

Maximum laser power to evaluate (W).

speed_min: f64

Minimum scan speed to evaluate (m/s).

speed_max: f64

Maximum scan speed to evaluate (m/s).

layer_thickness: f64

Layer thickness (m) — fixed during optimisation.

hatch_spacing: f64

Hatch spacing (m) — fixed during optimisation.

e_low: f64

Lower energy-density threshold for dense parts (J/m³).

e_high: f64

Upper energy-density threshold before keyhole (J/m³).

Implementations

impl ProcessWindowOptimizer

pub fn new( power_min: f64, power_max: f64, speed_min: f64, speed_max: f64, layer_thickness: f64, hatch_spacing: f64, e_low: f64, e_high: f64, ) -> Self

Construct a ProcessWindowOptimizer.

pub fn energy_density(&self, power: f64, speed: f64) -> f64

Compute volumetric energy density for a (power, speed) pair (J/m³).

pub fn porosity_score(&self, ev: f64) -> f64

Porosity score for a given energy density (lower is better, 0 = optimal).

Uses a quadratic penalty outside the [e_low, e_high] window.

pub fn roughness_score(&self, speed: f64) -> f64

Surface roughness score for a given scan speed (lower is better).

Higher scan speeds produce rougher surfaces (balling) above a threshold.

pub fn cost(&self, power: f64, speed: f64) -> f64

Combined cost for a (power, speed) pair.

pub fn optimise(&self, n_points: usize) -> (f64, f64)

Sweep n_points × n_points grid and return the (power, speed) with the lowest combined cost.
