]]>The post Pneumatic Cylinder Tutorial appeared first on DZynSource, LLC.

]]>When designing injection molds, it is very often desirable to use pneumatic cylinder to move objects, or act in place of springs. Pneumatic cylinders are used to separate plates, move side-action components, create false breaks, and much more. Because they are used so often, and I try to make engineering easier and faster, I have included a feature in the software for doing these calculations.

The pneumatic cylinder size calculator sizes the piston so that the force generated is twice what is actually needed. If the force is too low, the movement is sluggish due to being underpowered. If the cylinder is sized to large for the application, the object can also move too slowly because an excessive volume of air is needed to operate the cylinder.

You will also notice that the return force is always less than the forward force, as there is no air pressure acting on the area where the piston rod is located.

As with all feature in DZynSource Mold Engineering Software, the calculation is available in both Imperial and SI units (inch or metric).

I have also included the scfm calculation needed for valve sizing when working with pneumatics, as this is usually a consideration that needs to be, or should be, calculated or measured. The metric calculation returns the air volume in liters.

Here is a link to a tutorial on how to use the Pneumatic Cylinder feature:

]]>The post Calculate Optimum Diameter For Cutter Or Part appeared first on DZynSource, LLC.

]]>The equation used in this calculation is: Diameter = (SFM / RPM) / (Pi * 12)

where, SFM = Surface Feet per Minute,

RPM = Revolutions per Minute, and

Pi = 3.141592654

When using DZynSource Mold Engineering Software to do the calculation, go to “Machining Calculations” / “Surface Feet Per Minute” and then choose “Diameter” from the option boxes.

Enter the RPM’s and he surface feed per minute in the appropriate text boxes. Press Calculate. The answer appears in the Answer frame.

Use the Clear button to clear all fields, however this is not necessary in order to do another calculation. You may simply type over the previous entries.

]]>**Metric screw sizes are calculated as follows:**

- Minor diameter = Major diameter – (1.226869 x pitch)
- Pitch diameter = Major diameter – (.649519 x pitch)
- The tensile stress area = ((root dia + pitch dia) / 2)^2 * Pi/4

**Inch screw sizes are calculated as follows:**

- Minor diameter = Major diameter – (1.299038 x pitch)
- Pitch diameter = Major diameter – (.649519 x pitch)
- The tensile stress area = ((minor diameter + pitch diameter) / 2)^2 * Pi/4

Of course, you can download DZynSource Mold Engineering Software and not have to do these calculations yourself!
