Overview
ISO 23481:2021 - Tools for pressing - Cam driver plates defines the main dimensions and tolerances for plates used as cam drivers and slides in press tools. The third edition (2021) replaces the 2013 edition and clarifies several geometric features (for example, specifying radii in place of certain chamfers). The standard also prescribes a simple designation format for cam driver plates to ensure consistent identification across design, manufacture and procurement.
Key topics and requirements
- Dimensions and tolerances: Main sizes and tolerances are given by reference to the drawings in Figure 2 and the nominal sizes in Table 1 (dimensions in millimetres; surface roughness values in micrometres).
- General tolerances: Applies ISO 2768‑1 (general tolerances), specifically tolerance class m for unspecified linear and angular dimensions.
- Fasteners and features: Hexagon socket and screw details are referenced to ISO 4762 where applicable.
- Edges and radii: All edges of undefined shape must conform to ISO 13715; the 2021 edition updates some entrance and corner details to radii.
- Material: Material selection is left to the manufacturer’s discretion, allowing flexibility for different tool steels or hardened plates depending on application.
- Designation format: Standardized naming to simplify ordering and documentation. Example:
- Cam driver plate ISO 23481 - 100 × 170 × 60 (width × length × thickness in mm)
Practical applications and users
ISO 23481:2021 is intended for anyone involved in the design, manufacture, maintenance or procurement of press tooling components, specifically:
- Toolmakers and die designers specifying cam driver plates for press tools.
- Press-tool manufacturers and assembly shops ensuring interchangeability.
- Maintenance and tooling departments selecting replacement plates for cam drivers and slides.
- Purchasing and supply chain teams that require standardized product identification and dimensions.
Typical applications include cam-driven slides, progressive dies and other pressing tool subassemblies where repeatable geometry and fit are critical.
