Temco 0-M, 21-M 2002 Training Manual

Shop owners and CNC operators: you’ve got a 0-M or 21-M control on your Temco mill and you need to understand how it thinks. The Temco 0-M, 21-M 2002 Training Manual is the factory document that walks you through every G-code, reference point, and offset. None of that aftermarket guesswork. This is the same binder EMCO used in their training courses. It starts with reference points — M, A, W, R for the machine and N, P for the tool system. Page 2 diagrams the coordinate system and shows how to approach the reference point. If you’ve ever had a machine lose position after a crash, this section alone is worth the price.

Fanuc 0-M and 21-M Controller Layout

The first section of the manual shows the control panel layout. You get labeled buttons and screen locations. This is not a generic pic — it’s specific to the 0-M and 21-M variants used on EMCO machines. Knowing where the cycle start button is won’t fix a miswired coolant line, but it sets the foundation. Next you move into reference points and coordinate systems.

What Reference Points Does the Manual Detail?

Reference points M, A, W, R and tool system points N, P. The manual explains how to reference the machine and what each point means. You get symbols and shorthand for marking prints. This is critical for homing the machine after power loss. Without these specs you risk crashing into hard stops or losing your work coordinate system.

Tool Offsets and Zero Shift Adjustments

Zero shift offset No.00 and additive offsets G54-G59. The manual shows the combination of zero offset and additive offset, and how the coordinate system maps to the workpiece. If you’ve ever tried to set a work offset on a 0-M without a probe, you know the headache. This training manual gives the logic. It also covers tool offset data entry — length and radius compensation. That section alone saves you from trial-and-error touching off tools.

3 Key G-Code Groups Explained

The manual covers G00 rapid traverse, G01 linear interpolation, and the circular interpolation G02/G03 with I,K parameters. Also radii “R” and chamfers “C”. Then drilling cycles: G73/G83 chip breaking, G74/G84 tapping, G81-G89 cycles with dwell and spindle stop. For thread cutting, G33 is there. That’s a lot of ground for 37 pages. It also handles plane selection G17-G19, polar coordinates G16, and cutter radius compensation G40-G42. Every G-code includes a slide with a diagram and explanation — exactly what you need when programming at the machine.

Understand the Drilling Cycles Before You Start

Drilling cycles are where many crashes happen. The manual details G73, G83, G81, G82, G85, G86, G88, G89. It covers withdrawal plane, dwell, spindle stop. These specs are straight from the factory. Using the right cycle can save you from broken drills. Tapping cycles left/right (G74/G84) are also included with direction logic. The manual also covers precise stop modes G09, G61, G64 and two withdrawal options G98/G99. That level of detail keeps your spindle running instead of replacing toolholders.

It also covers M98/M99 subroutines and G90/G91 programming.

Source Authenticity: Why OEM Matters for CNC Training

This is a Temco training manual, not a third-party rehash. The document is multilingual (German, English, French, Italian), published 2002 by EMCO MAIER. Ref. Nr. VS 9973. If you’ve ever used an aftermarket manual that got a G-code wrong or omitted critical safety notes, you’ll appreciate the OEM source. For the price of a hour of machine downtime, you get the facts. The 37 pages are direct scans of the training slides used in EMCO’s industrial training systems. No editing, no translation errors.

If you also work on Manual Transmission systems, you’ll notice how G-code concepts translate to transmission component machining.

Is this manual in English?

Yes. The manual includes English alongside German, French, and Italian.

Does it cover all G-codes for the 0-M and 21-M?

It covers the main G-codes you’ll use for milling: linear and circular interpolation, drilling cycles, tapping, thread cutting, cutter radius compensation, scaling, mirroring, polar coordinates, plane selection, dwell, and precise stop. It also covers M98/M99 subroutines and absolute/incremental programming. That’s the core set for operating and programming the control. But it’s a training manual, not a full programming reference. If you need every possible G-code or machine-specific parameters, you’ll want the full programming manual. However, for the everyday operations this manual gives you the solid foundation with clear diagrams and examples from the factory curriculum.
