SURFACE PLATE CAL-O-MATIC 3000

V1.5 · T.O. 33K6-4-33-1 Planekator Method
Implementation basis: T.O. 33K6-4-33-1, 30 January 2013, “Surface Plates - Planekator Method.” The app preserves the procedure’s stated limits and flags places where the source does not define enough information for a safe automatic decision.

Inner diagonal—
Auto uses the procedure’s “18 inches and smaller” rule first, then compares the marked-surface diagonal with the selected Planekator reach to suggest Preferred vs Alternate.

Dimensions are used for data-grid generation and the procedure diagram. They do not replace the technician’s physical marking and positioning requirements.

Instruction Visuals

Open the illustrated preliminary-operations poster for stabilization, environmental control, cleaning, perimeter marking, method selection, Planekator setup, Planekator corrections, and repeatability.

Temperature Stabilization & Calibration Environment

Cleaning / Wait Controls

The procedure requires the three-step cleaning sequence and a 4-hour wait before calibration, except it directs small plates (18 in and under) to proceed to paragraph 4.2 after cleaning.

Instruction Visuals

Open the illustrated uniformity-verification poster for the Repeat Reading Gage scan pattern, approximate spacing, return-to-start check, and chart-preparation flow.

Uniformity Verification - Repeat Reading Gage

Rows ~12 in apart; readings ~5 in apart; start ~2 in from edge.

Observed range—
Return-to-start checks—
The uploaded procedure specifies the uniformity measurement pattern and the return-repeat requirement, but does not state a separate numerical acceptance limit for the uniformity readings themselves. This app therefore charts the readings without inventing one.

Instruction Visuals

Use the method-specific poster that matches the current flatness method selection.

Procedure Diagram

Nameplate direction is shown as North for procedure correspondence; use the physical orientation recorded on the setup tab.
