Manufacturing and process in Svelte

A machined bore with a tolerance driving capability, drifting in one shift

spec · grid.statistics.capability

This is a machined-bore dataset with a tolerance driving a capability figure, and the process drifting within a single shift. It shows manufacturing data judged against its spec in real time, so a drift out of tolerance shows as it happens.

Building…
Loading a live grid…

This is the Svelte version. A use action attaches the grid to a plain element, so no framework runtime is passed in and the component stays small, while the configuration is ordinary Svelte state.

The configuration

<script>
  import { createGrid } from 'https://cdn.latticegrid.dev/lattice-grid@1.108.0/lattice-grid.esm.min.js';
  import createLatticeAction from 'https://cdn.latticegrid.dev/lattice-grid@1.108.0/modules/svelte.esm.min.js';

  const lattice = createLatticeAction({ createGrid });

  let out = '';

  const config = {
    rowKey: 'id',
    toolPanel: { side: 'left', panels: ['columns', 'filters', 'statistics'] },
    columnDefaults: { filter: true },
    columns: [
      { field: 'part', title: 'Part', layout: { pin: 'start', width: 120 } },
      { field: 'shift', title: 'Shift', filter: { type: 'set' } },
      // The spec drives process capability and the control chart.
      { field: 'bore', title: 'Bore', type: 'millimetres', total: 'median',
        spec: { lower: 9.5, upper: 10.8, target: 10 } },
      { field: 'speed', title: 'Spindle', type: 'rpm', total: 'avg' },
      { field: 'torque', title: 'Torque', type: 'torque', total: 'max' },
    ],
    formatting: {
      bore: [
        { id: 'b-out', when: { op: 'notBetween', value: 9.5, value2: 10.8 }, style: { background: '#fbeceb' } },
        { id: 'b-z', when: { op: 'zAbove', value: 2 }, style: { background: '#fff4e5' } },
      ],
    },
    rows,
    // onGrid hands over the live grid the moment it is created. baseline fixes
    // the limits on the first 40 readings, so a later tool-wear drift
    // separates Cpk from Ppk rather than widening the limits to absorb it.
    onGrid: (grid) => {
      const report = () => {
        out = JSON.stringify(grid.statistics.capability('bore', { baseline: 40 }), null, 2);
      };
      grid.on('filter:changed', report);
      report();
    },
  };
