Capability against a tolerance in Angular

Cp, Cpk, Pp and Ppk from one column declaration

grid.statistics.capability(col, { baseline })

This grid computes Cp, Cpk, Pp and Ppk from a single column declaration with its tolerance. It tells a quality engineer whether a process fits within its spec, straight from the readings, without exporting to a separate tool.

Building…

Loading a live grid…

This is the Angular version. A standalone component takes the whole configuration through one config input, surfaces grid events as outputs, and exposes the live grid on a getter for anything the inputs do not cover.

The configuration

import { Component, ViewChild } from '@angular/core';
import { bootstrapApplication } from '@angular/platform-browser';
import { createGrid } from '@toclocoinc/lattice-grid';
import '@toclocoinc/lattice-grid/css';
import { LatticeGridComponent, provideLattice } from '@toclocoinc/lattice-grid/angular';

const columns = [
  { field: 'part', title: 'Part', layout: { pin: 'start', width: 110 } },
  // The spec declares the tolerance; capability reads it.
  { field: 'bore', title: 'Bore', type: 'number', total: 'median',
    spec: { lower: 9.5, upper: 10.8, target: 10 } },
];

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [LatticeGridComponent],
  template:
    '<lattice-grid [config]="grid" (grid-ready)="onGridReady()" style="display:block;height:440px"></lattice-grid>' +
    '<pre style="margin-top:12px">{{ out }}</pre>',
})
export class AppComponent {
  @ViewChild(LatticeGridComponent) gridRef!: LatticeGridComponent;
  out = '';

  grid = {
    rowKey: 'id',
    columns,
    rows: [/* machined bore measurements */],
  };

  // capability reports Cp, Cpk and the rest against the column's declared spec,
  // read straight from the live grid. The grid is created once the view has
  // rendered, so the live instance arrives on grid-ready rather than in
  // ngAfterViewInit.
  onGridReady() {
    const grid = this.gridRef.grid;
    this.out = JSON.stringify(grid.statistics.capability('bore', { baseline: 20 }), null, 2);
  }
}

bootstrapApplication(AppComponent, {
  providers: [provideLattice({ createGrid })],
});
