Full title and description

STB VDI 3323 E 2020-08 — Applicability of hard cutting materials for metal cutting processes (German title: Anwendungseignung von harten Schneidstoffen). This entry refers to the VDI draft (E) published August 2020 that provides a uniform way to describe where and how hard cutting materials (e.g., carbides, ceramics, CBN, PCD) are applicable in chip‑removing machining operations.

Abstract

This guideline (Entwurf) defines communication aids to describe the versatile application possibilities of hard cutting materials. It classifies workpiece materials and chip‑removing machining processes using code letters and application diagrams so that the suitability of individual cutting‑material grades can be described uniformly in tables or data sets according to defined rules.

General information

• Status: Draft (Entwurf, indicated with prefix "E").
• Publication date: August 2020 (2020-08).
• Publisher: VDI (Produktion und Logistik / Verlag des Vereins Deutscher Ingenieure).
• ICS / categories: 25.100.01 — Cutting tools in general.
• Edition / version: E VDI 3323 (draft version published 2020-08).
• Number of pages: 11 pages.

Scope

VDI 3323 (E) provides a standardized framework to communicate the application suitability of hard cutting materials across metal‑cutting processes. The document covers classification of workpiece materials and chip‑removing processes, assigns code letters for categories, and specifies rules for preparing application diagrams, tables or data records so manufacturers, tool designers and users can compare and document which cutting‑material grades are appropriate for given operations. It is intended as a communication tool rather than a prescriptive test procedure.

Key topics and requirements

• Classification of workpiece materials relevant to machining (groups and coding).
• Classification and coding of chip‑removing machining processes (turning, milling, drilling, etc.).
• Assignment of code letters for cutting‑material grades and conditions of use.
• Application diagrams and tabular/data‑record formats for documenting suitability.
• Rules and conventions for preparing uniform, comparable suitability descriptions across suppliers and users.

Typical use and users

This guideline is used by cutting‑tool manufacturers, tooling engineers, process planners, production engineers, and technical purchasers to standardize how tool materials are presented and selected for machining tasks. It is also useful for technical documentation teams and software/data providers that maintain tooling databases. The document helps improve communication between material producers, tool makers and end users when specifying or comparing cutting‑material options.

Related standards

VDI 3323 (2020 draft) updates and complements earlier VDI guidance on applicability of hard cutting materials (an earlier version exists from 1996). It is related to VDI handbooks on production technology and to ICS/ISO work in the cutting‑tools domain (ICS 25.100 family). Users selecting indexable‑insert designations or comparing material classes may also consult relevant ISO standards and VDI handbook volumes referenced in the VDI product listing.

FAQ

Q: What is this standard?

A: VDI 3323 E 2020-08 is a VDI guideline draft (Entwurf) titled "Applicability of hard cutting materials for metal cutting processes" that defines a uniform way to describe where and how hard cutting materials are suitable for chip‑removing machining.

Q: What does it cover?

A: It covers classification of workpiece materials and machining processes, coding conventions (code letters), and formats (application diagrams, tables or data records) to document and communicate the suitability of specific cutting‑material grades. It is intended as a communication and documentation aid rather than a test method.

Q: Who typically uses it?

A: Tool manufacturers, tooling and production engineers, process planners, purchasers of cutting tools, and technical documentation/data‑management teams who need standardized descriptions of cutting‑material applicability.

Q: Is it current or superseded?

A: The 2020 document is published as a VDI draft (E) from August 2020; the earlier VDI 3323 edition from 1996 remains part of the historical record. For the absolute current legal/technical status (final approval, withdrawal, or replacement), consult the VDI standards catalogue or VDI publisher because the draft/objection timeline and finalization may have changed since publication. (VDI indicated the objection period ended January 31, 2021.)

Q: Is it part of a series?

A: Yes — VDI 3323 is part of the VDI production/production‑technology rule set and is referenced alongside VDI handbook volumes on production technology and manufacturing processes; it sits within the general ICS cutting‑tools family (ICS 25.100.01).

Q: What are the key keywords?

A: Hard cutting materials, cutting‑tool materials, carbide, CBN, PCD, applicability, application diagrams, machining processes, VDI 3323, tooling classification.
