New version of PipeDesigner

The new PipeDesigner program (2014-02-26) has been released with a export feature to ConeDesigner.

See the tutorial below for detail on getting the data for ConeDesigner.

Example: input data (by default in the GUI) :

Displacement : 124.90cc
Exhaust duration : 193.00°
Exhaust port height :  25.00mm
Exhaust port width :  35.00mm
Cylinder length :  52.00mm
Desired Power:  27.00HP
Engine Rotation : 9800.00 rpm
Coefficient Horn :   1.60

Step 1 => Click on “Compute Pipe” button => Result below

– Blair formulas
– Metal thickness 0.8mm (by default)
D0 :  37.41 mm
D1 :  37.41 mm
D2 :  50.12 mm
D3 :  72.49 mm
D4 :  94.58 mm
D5 :  94.58 mm
D6 :  21.06 mm
D7 :  21.06 mm
L01 :  44.64 mm
L12 : 265.77 mm
L23 : 176.86 mm
L34 :  88.91 mm
L45 : 106.31 mm
L56 : 231.94 mm
L67 : 231.94 mm
Total length : 1146.37 mm

Step 2 => Click the “Pipe Designer” button

– Put these data for the pipe profile for the 8 sections
Arc X : Rayon,Angle
Arc 0 : 44.640000,0.000000
Arc 1 : 253.800000,60.000000
Arc 2 : 176.000000,0.000000
Arc 3 : 88.910000,0.000000
Arc 4 : 36.310000,0.000000
Arc 5 : 35.000000,0.000000
Arc 6 : 35.000000,0.000000
Arc 7 : 950.000000,14.000000
Arc 8 : 950.000000,14.000000
– The following files will be created automatically :
– txt file for the parameters => PipeDesginer.txt
– DXF file for the pipe profile => PipeProfile.dxf

Step 3 => Open the file PipeDesginer.txt and he should contain the following data

You could verify that the diameters in this sample are exactly the same as the ones at step 1 because I pay attention to lengths of the 8 sections of the pipe shape (the cylindrical section has been split in 3 parts!!!)

Arc X : Rayon,Angle,DIn,Dout
Arc 0 : 44.640000,0.000000,37.409979,37.409979
Arc 1 : 253.800000,60.000000,37.409979,50.120635
Arc 2 : 176.000000,0.000000,50.120635,72.383361
Arc 3 : 88.910000,0.000000,72.383361,94.372427
Arc 4 : 36.310000,0.000000,94.372427,94.584018
Arc 5 : 35.000000,0.000000,94.584018,94.584018
Arc 6 : 35.000000,0.000000,94.584018,94.584018
Arc 7 : 950.000000,14.000000,94.584018,21.063705
Arc 8 : 950.000000,14.000000,21.063705,21.063705

DIn = Input diameter of the cone
DOut = Output diameter of the cone

Step 4 => Run ConeDesigner to create the unfold pattern of section Arc1

D2 = DOut = 50.120635mm
D1 = DIn = 37.409979mm
Angle A = Angle =60°
Radius R = Rayon = 253.80mm

How to print over A4 paper with A9CAD

Here a little tutorial for print DXF at 1-1 scale when they are bigger then A4 page.

Here a straight cone designed using Cone Designer.

Here the DXF in A9CAD

Go to Print Setup in File menu

Print Setup window

Remove the Scaled to fit option and set 1mm to 1mm

Then hit Refresh button

Now the drawing is at the real size and goes over the page

Hit the Windows radio button then choose the window to be printed

Now the drawing windows is ready to be printed and to the same for the other part. Assemble the printed paper sheets.

Pipe designing by Noël

I share with you the craft work of a PipeDesigner user to develop some pipes for his 50cc race moped.

He starts with the realization of an header in order to test his equipment, to see how the metal sheet is deforming and the modifications of the curvature of the pipe center line.

Then, he cuts the two half pipes, bend the side at 90°, weld the sheets together. When the high pressure and purge valve are on, starts the shape building.

The result is very good so well done the artist.

Little help to Cone Designer user

Aside

To help a user on Cone Designer, I’ve done some computation and paper rolling.

Input data :

  • D1 -> 80mm
  • D2 -> 50mm
  • A -> 180°
  • R -> 86mm
