New Release of ALMCOM 5.0

The German company Peening Accessories has waited a few years to introduce its new version of ALMCOM 5.0, software to calculate the Almen saturation curve. There are a number of significant improvements, which allow for benefits from such a tool in a fashion not possible before.

Development of new a Function for the Curve Fitting

While a normal curve fitting with a logarithmic function was used to calculate the Almen curve, a completely new approach was realised for ALMCOM 5.0. Hundreds of Almen test points have been analysed. Based on those test points the function is able to determine exactly what  a typical Almen saturation curve is supposed to look like.
This fact gives one great advantage compared to a standard fitting. A user can already, after entering two test points, see an approximate result of the complete curve. This includes T and 2T. That of course does not mean that he will not have to run more test points, however, the operator gets a guidance in terms of how long he has to peen a test strip to develop a proper curve. That certainly will save time since it will avoid the peening of unnecessary test points.

Software with direct Interface to Almen Gage

ALMCOM 5.0 can directly communicate with the digital Almen gages of Peening Accessories. Using either a USB or a RS232 interface, the Almen gage can be connected with the software. By pressing a button on the dial of the gage, the value measured will be transferred into the ALMCOM software. This option will eliminate possible mistakes by typing errors.

Up to 30 Almen Saturation Curves in one Spread Sheet

6 different Almen curves can be stored in one spread sheet. E.g. if a work piece has 6  positions for which Almen curves have to be developed, they can all be stored in the same file. For each position up to 5 test points can be taken. On request the software takes the mean value of selected test points. That gives a total of 30 curves. All data can be stored on the computer. The writing of PDF's files allows the data to be shared with a third party and can be integrated into other programs.  

Deflection of unpeened Almen Strips can be taken into Account

An Almen strip has, with very few exceptions, always a certain deflection. Such deflections are defined in different specifications. If a user wants to integrate the deflection of the strip into the measurement, it can be entered into the software. That means after measuring the peened strip, the program will take the original deflection into account.

Data Sheet for Almen Test Points

In the data sheet for Almen test points all measurements can be entered. A maximum of 15 points can be included. The Almen intensity values can either be keyed in "inches" or "mm". For the x-axis (time-axis) of the function there are 4 different input possibilities. Either "time", "speed of nozzle over surface", "number of peening strokes" or "revolution of turn table". It is possible to enter up to 5 test series of Almen values.

General Protocol

The "General Protocol" allows an input of all technical and logistic data which are somehow related to the Almen saturation curve. Since every customer wants to save other data, the user of Almcom can edit and change titles and entries of the protocol in what ever way required. However, the person who wants to edit the protocol will have to enter a password.

Customer Logo

Many customers had previously requested that the printed Almen curve would include their own logo, rather than the one of Peening Accessories. This can be an advantage, especially if these documents have to be submitted to a third party,. A new function allows the loading of a personal logo into the software.

Set-up depending on Customer Requirements

The language, as well as the measure units can be changed (English-German, Inch-mm). Depending on what type of Almen strip is used, A-, N-, and C-Almen can be selected. Furthermore a range of tolerance can be determined. The software will always calculate if a test point is within a defined reach to the curve fitting and if not, high light that there may be a problem with a single test point.


This new software has indeed a number of new functions, which not only make a reading of T and 2T more accurate, but also will save time during the process of developing an Almen curve.
