PartsPerArea

The app calculates the maximum number of similar parts of a given shape and size that can be accommodated on a given rectangular area.

This app is intended for all users who want to cut identical parts out of a rectangular, flat material. The app user receives information about the material requirements and the optimal placement of the parts.

The calculated maximum number of parts and the percentage utilization of the area are displayed as the result. The placement of the parts on the area is shown graphically.

Special features:

• 2D cutting optimization for parts of any shape

• Consideration of a tool diameter or a minimum safety distance between the parts

• Easy to use: If the accuracy requirement is slightly reduced, a photo of the part is sufficient

• Data entry and analysis result within 90s

In addition to rectangles and circles, profiles that can have any shape can be selected as parts. For the "Profile", the description of the part must be imported.

Available Import options:

• NC program with G-code instructions

• Graphic as bitmap file

• Photograph

Placing methods:

• Standard: No rotation

• Optimized: The parts are rotated

Input parameters for the profile optimization calculation:

• "Area Length"

• "Area Width"

• "Tool diameter"

Start of optimization (button "Calculate"):
After entering the parameters and importing the profile description, the optimization calculation can be started.

If an invalid parameter configuration is detected, an error message appears with instructions on how to fix it.

Import of a profile part description (button "Import"):

The description of the part must be imported either as a bitmap file (*.jpg, *.jpeg, *.gif, *.bmp, *.png) or in the form of an NC program file (*.txt).

Photo as profile part description (button "Photo"):

A photo of the part can also be used as a profile description. It must be noted that image distortions can occur when taking photos.

After taking photos, a rectangular image section can be defined using a cropping function. Only this image section is then evaluated.

Requirements for a usable photo:

The part must stand out clearly from the background of the image. The background must also be as uniform and unicoloured as possible.

When photographing objects, it is recommended to use a white sheet of paper as a background. Any shadow of the object can be minimized using the flash function. Light problem areas can be covered with dark adhesive tape.

Special features of bitmap import and photography:

When importing a bitmap file or using a photo, the user must also specify the dimensions of the part ("length of the part") or ("width of the part"), as no information about the dimensions of the part is available.

To determine the part dimensions, the part can be aligned by rotating it.

Import of a NC Program Profile Part Description:

The evaluation of an imported NC program offers the highest calculation accuracy.

The length of the NC program is limited to 1000 NC blocks (linear or circular).

Details on importing an NC program can be found in the help of this app.
