Tool role and boundaries

Deep Hole Pecker Macro is not a one-shot number widget. It is an engineering baseline tool for real shop-floor decisions. Build deep-hole peck cycles with local peck strategy rules and local time calculations. This tool generates parametric macro templates for CNC controllers, requiring dry-run validation before production use.

Treat every output as a first-pass candidate, not an immediate production command: run defaults first, tune one variable at a time, and record machine, tooling, fixture, and material-lot context.

Fast baseline workflow

  1. Run once with defaults to confirm units and expected behavior.
  2. Lock constraints first (dimensions, machine limits, setup boundaries), then tune controls.
  3. Change one key variable per iteration and record why it changed.
  4. Check primary outputs against machine capability before secondary metrics.
  5. Validate first piece with conservative override before moving to target cycle.
  6. Store accepted values with revision tags so shift handoff stays reproducible.

Input strategy

Use a three-layer input model:

  • Constraint layer: dimensions, tolerances, travels, clamping, controller limits.
  • Control layer: speed, feed, engagement, compensation, cycle parameters.
  • Target layer: takt time, cost, scrap risk, tool-change frequency.

A common failure mode is pushing control values before constraints are stable. Lock constraints first, then build a stable operating window with small increments.

Output interpretation

Interpret results in order: primary safety checks first, then stability, then economics.

  1. Safety: no machine, tool, or fixture limit violations.
  2. Stability: load, thermal, and vibration behavior remains controlled.
  3. Economics: cycle and cost align with shift target.

Current focus outputs include Peck sequence, Variable depth steps, Local cycle template. If numbers conflict with floor behavior, verify units and inputs before changing strategy.

NC program notes

This page outputs Fanuc and Haas style templates. Before release, enforce these checks:

  • Confirm controller support for macro variables, cycles, and trig syntax.
  • Verify modal preamble (for example G17, G90, G40, G49, G80).
  • Review clearance plane, retract height, and feed variables against setup reality.
  • First run should be dry-run, single-block, and reduced override.

Typical failure modes and fixes

  • Sudden output jump: verify units, decimal precision, and input ordering first.
  • Unexpected trend: inspect workholding, tool condition, and thermal stability before retuning.
  • Big machine-to-machine delta: compare servo behavior, coolant coverage, spindle health, and compensation tables.
  • Shift handoff instability: enforce revision logging for program, tool, and parameter timestamp.

Keep rollback points and use single-variable increments to avoid coupled uncertainty.

FAQ

Can outputs be used directly for production?

Not immediately. Validate first piece, then short-run stability, then release to full production.

Why does floor behavior differ from computed values?

This is expected. Material lot, tool wear, thermal state, and machine dynamics all shift outcomes.

When should I recalculate?

Recalculate whenever tooling, fixturing, material lot, controller parameters, or takt target changes.

Final recommendation

Use Deep Hole Pecker Macro inside a fixed loop: baseline, first-piece validation, single-variable tuning, parameter freeze, and revision tracking. The outcome is not just one result but a repeatable process capability.
