Measuring!the!Arc!Height!of!a!Peened!Almen!Strip!

The!following!steps!should!be!performed!on!the!standard!Almen!strips!and!the!mini-strips.!

Step!One!–!Zero!the!Almen!Gage!

1. Push!the!ZERO/ON!button!to!turn!the!gage!“ON”.!!

2. Place!the! Zero!Block! on! the! gage! with! the! indicator! tip! touching!

the!small!side.!Push!the!ZERO/ON!button!to!achieve!0.000!mm!in!

the!display.!

Step!Two!–!Perform!Pre-Bow!Compensation!

If!your!shot!peening!procedure,!such!as!process!development!or!system!

capability! studies,! requires! higher! intensity! accuracy,! pre-bow!

compensation! may! be! used.! This! technique! can! provide! an! additional!

reduction! in! process! uncertainty.! A! pre-bow! compensation!ensures!that!

only!the!net!difference!in!arc!height!of!a!peened!Almen!strip!is!plotted!on!

a!saturation!curve.!To!perform!pre-bow!compensation:!

1. Zero!the!Almen!gage!and!then!place!the!unpeened!Almen!strip!on!

the!gage!and!record!its!value.!!

2. Be!sure!to!note!if!value!is!positive!or!negative!and!write!the!value!

on!the!opposite!side!of!the!strip.!!

3. Do! not! peen! the! side! of! the! Almen! strip! with! your! handwritten!

note.!!

4. A!positive!number!is!subtracted!from!the!arc!height!reading!

after!the!strip!has!been!peened.!A!negative!number!is!added!

to! the! arc! height! reading! after! the! strip! has! been! peened.!

For!example:!

a) If!the!pre-bow!is!+2! and!the! arc!height!reading!is! 10,!

the!adjusted!arc!height!reading!is!8!

b) If! the! pre-bow! is! -2! and! the! arc! height! reading! is! 10,!

the!adjusted!arc!height!reading!is!12!

In! summary,! most! peening! applications! can! tolerate! the! SAE! J442!

pre-bow!bias!of!±0.001”!for!N!and!A!strips.!If!this!tolerance!level!is!

too! high,! you! can! apply! the! pre-bow! compensation! discussed!

above.!!

Step!Three!–!Measure!the!Arc!Height!

1. Place!the! peened!Almen! strip! onto!the! measurement!position! with!

the!indicator!tip!touching!the!non-peened!side!(concave!side)!of!the!

strip.!Record!the! value!of! the!arc! height! shown! in!the! display!or,! if!using!pre-bow! compensation,!the!arc!

height!shown!in!the!display!with!the!pre-bow!compensation!applied.!

2. Remove!the!strip!and!place!it!once!again!on!the!gage.!Do!this!three!(3)!times!to!assure!an!accurate!reading.!!

3. When!finished,!push!and!hold!the!M/OFF!button!for!three!(3)!seconds!to!turn!the!gage!“OFF”.!(The!gage!

automatically!turns!“OFF”!if!it!is!not!active!for!15!minutes.)!
