Surface Texture Control

2011-08-04

CURRENT

J449_201108

SAE J448, Surface Texture, has been set up for precision reference specimens using a controlled surface profile to obtain reproducible roughness values. These specimens are for instrument calibration. Appropriate symbols for roughness, waviness, and lay have also been standardized (ASA B46.1-1962 and SAE J448). For production control, especially from one geographical location to another, means are required to facilitate the inspection of surface characteristics called for by specifications which include not only roughness but profile waviness and lay. In order to integrate the requirements of the designer with the actual production of surfaces, a second grade of control standards must be adopted which will be functional in nature for the specific product being manufactured. These control standards may be Calibrated Pilot Specimens (actual parts with satisfactory texture) or Roughness Comparison Specimens (ASA B46.1-1962).

DEFINITIONS FOR MACROSTRAIN AND MICROSTRAIN

1985-08-01

HISTORICAL

J932_198508

In the analysis and measurement of residual stresses of materials, it has been noted that there are frequently differences in interpretation of the terms "macrostrain" and "microstrain." To assist communication among research personnel in this area, definitions for these two terms are suggested by the Fatigue Design and Evaluation Committee of SAE. Since "macrostress" is commonly computed from "macrostrain" in residual stress analysis, to be consistent, the definitions given are for "macrostrain" and "microstrain."

SAE Manual on Blast Cleaning

2022-09-23

CURRENT

J792_202209

Blast cleaning may be defined as a mechanical pre-treatment process in which a suitable stream of solid particles is propelled with sufficient velocity against a work surface to cause a cleaning or abrading action when it comes in contact with the workpiece. Blast cleaning may be employed for a variety of purposes. It is a well-established method for removing sand from castings and burrs or scale from forgings, mill products, or heat treated parts; to promote machinability; and to minimize the possibility of interference in actual operation. In addition to this use, blast cleaning also produces a suitable surface for downstream industrial coatings. All these objectives are often accomplished in the one operation. As a general understanding, this document pertains to blast cleaning only. Any reference to shot peening or other processes is only to explain a context or concept related to blast cleaning.

Procedures for Using Standard Shot Peening Test Strip

2003-01-09

HISTORICAL

J443_200301

This SAE Recommended Practice provides uniform procedures for using the standard shot peening test strips reported in SAE J442. Standard test strips are used to establish saturation, determine intensity, monitor repeatability of the shot peening machine operations, and can be used to predict a desired result on a part. It is recommended that the standard test strip A be used for intensities that produce arc heights of 0.10mm A (0.004 inch A) to 0.60 mm A (0.024 inch A). For intensities below 0.10 mm A (0.004 inch A), the standard N strip is recommended, and for intensities above 0.60 mm A (0.024 inch A), the standard C strip is recommended. The process of shot peening, in common with many other processes, cannot at present be adequately controlled by nondestructive inspection of the peened parts, therefore, it is necessary to control the process itself to achieve consistent, reliable results.
