Electronic method for calibrating peening intensity

A method of calibrating an electronic sensor for peening intensity comprising the steps of:

• establishing a range of desired intensity levels for peening;
• setting parameters of a blast stream to achieve intensity levels within said range of desired intensity levels;
• subjecting test strips to blast streams to peen said test strips at each said intensity level within said range of desired intensity levels;
• measuring an arc of said test strips from said blast stream after said strips have been peened at each said intensity level to determine intensity;
• subject said sensor to said blast streams at each said intensity level within said range of desired intensity levels and record an output signal of said sensor corresponding to each said intensity level;
• and
• correlate each said intensity level to said corresponding signal and create a chart correlating each intensity level to each said corresponding signal.

A method of calibrating an electronic sensor for peening intensity comprising the steps of:

• establishing a desired intensity level for peening;
• setting parameters for a blast stream corresponding to said desired intensity level;
• shot peening test strips in said blast stream;
• measuring arcs of said test strips shot peened in said blast stream to determine said intensity level;
• shot peening said sensor in said blast stream set at said parameters corresponding to said desired intensity level and recording an output signal of said sensor;
• determining whether other intensity levels should be measured;
• setting second parameters for another blast stream corresponding to said other intensity level upon determining other intensity levels should be measured;
• shot peening test strips in said another blast stream;
• measuring arcs of said test strips shot peened in said another blast stream set at said second parameters corresponding to said other intensity level and recording a second output of said sensor;
• correlating each said intensity level at which said sensor was peened with said output signals of said sensor;
• setting a roto-flap peening device to said intensity level;
• roto-flap peening a test strip;
• measuring said test strip that was roto-flap peened to verify intensity level;
• peening said sensor with said roto-flap peening device set at said intensity level;
• and
• measuring the output of said sensor.
