Component Specifications

Definition
A reference feature is a precisely manufactured physical element on a machine or workpiece that serves as a datum for establishing dimensional relationships, ensuring alignment accuracy, and facilitating repeatable positioning during manufacturing, assembly, or inspection processes. It provides a stable, measurable point or surface against which other components or measurements are compared.
Working Principle
The reference feature operates on the principle of establishing a fixed, known geometric datum. It provides a consistent physical benchmark that eliminates cumulative errors by allowing all subsequent measurements, alignments, or component placements to be referenced back to this single controlled feature, ensuring dimensional integrity throughout the manufacturing process.
Materials
Typically made from hardened tool steel (AISI D2, A2), stainless steel (304, 316), carbide, or ceramic materials to ensure dimensional stability, wear resistance, and corrosion resistance. Surface hardness typically ranges from 58-65 HRC for steel components.
Technical Parameters
  • Load Capacity Varies by application (typically 50-5000 N)
  • Surface Finish Ra 0.4 μm or better
  • Dimensional Tolerance ±0.005 mm
  • Flatness/Straightness 0.01 mm/m
  • Temperature Stability Coefficient of thermal expansion < 11.5 μm/m·°C
Standards
ISO 1101, ISO 5459, ASME Y14.5, DIN 7167

Frequently Asked Questions

What is the difference between a reference feature and a locating feature?

A reference feature establishes a primary datum for measurement and alignment, while a locating feature physically positions components relative to that datum. Reference features provide the coordinate system; locating features work within it.

How often should reference features be calibrated?

Calibration frequency depends on usage and environment. In precision manufacturing, reference features should be verified monthly or after every 500 operating hours, with full recalibration every 6-12 months.

Can reference features be repaired if damaged?

Minor surface damage can sometimes be re-machined or lapped, but significant damage typically requires replacement as the original dimensional integrity cannot be fully restored.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
