Define Casting Style

DynaRod User's Guide Preface How to use DynaRod Trouble Shooting Table of Contents

Up View and Delete Castin Entry

Function General

This feature allows users to design or define any casting style, that is, how a rod moves in casting.  All the calculations under Dynamic Deflection/Stress are made based on this casting definition.  A well designed casting will show a realistic realization of an actual scene.

Status of screen display

When opened this function, if the excel output for the rod is already made before, the screen shows the contents of existing file.

If this function is first used for the rod, blank casting style panel is shown.  User must complete the definition of casting style at first.

How to use

This is the window to define or design a casting style.

Casting Style auto Loading feature

It is somehow difficult for a new user to define a casting style from scratch, the  recommended way is to utilize "invoking" feature of pre-defined casting style and show it on this window.  

You can see where the feature is located on the panel above (lower left).  You can select one of registered casting styles by pull down menu of "Call existing Casting Style" combo box.  The above panel shows "Forward Cast" definition which is invoked through this feature.

There is another feature for this, Register the defined casting with name.  This feature allows you to modify the invoked casting style and name it differently and save it.  To delete some entry in the casting style, you can View and Delete the entry too.

Normal Rod Speed

In DynaRod, user can define any kind of rod movement in any kind of rod speed.  However, it is important to consider what is the normal and standardized rod speed.  

Considering the need of comparison with statically calculated result and people in rod making society, it is good to implement the unit of the rod speed = 4G.  But if user wants to simulate various situations, you can generate any rod speed here.

As each part of a rod has its own direction, distance, we need to decide one position to have a measurement of rod speed.  This feature uses the most top position of tip section as a representative point of the rod.  You can see such words on the panel as "Tip Top Velocity", "Tip Top Acceleration", etc..

The rod speed as a whole is displayed at the bottom of "Total" column.  (in Red Circle above).  This is the total of added acceleration toward the previous phase at each phase and is shown in G unit .(equivalent acceleration to gravity) 

To acquire a desired rod speed in G, it is done by increasing or decreasing the time duration until the G unit becomes what you desired. ( in Blue Circle above)

Defining your own casting style 

There are two methods to create your own casting style as follows;

Invoke registered casting style, modify it, and save it
Create your own style from scratch

How to specify

How to specify is quite same in either method.

General rule:

Total Amount    specifies total amount of movement with (+ , -) for direction

+ value    means from right to left, from up to down 
- value    means from left to right, from down to up

Start Amount   

specifies start position.  number is the point on XY graph with 1 feet scale.
the center of the XY graph is at X=0.  Y is above 0, no - value for Y axis.
matching part of a rod to the start position  is the top of rod Grip.  

For each raw :

Rod core Angle

Total Amt    total rotation angle
Start Amt    start angle on the XY graph from the point (X=0,Y=0)

Grip Horizontal Move

Total Amt    total horizontal distance in feet (or meter)
Start Amt    start position of Grip top on X axis in feet (or meter)

Grip Vertical Move

Total Amt    total vertical distance in feet (or meter)
Start Amt    start position of Grip top on Y axis in feet (or meter)

Time Allotted

Total Amt    specifies the time duration of whole movement
by changing this amount, we can change acceleration of whole
Start Amt    always zero

Allocation of Total Amount to each Phase

Rod movement is defined in 4 phases.  User can allocate the percentage of total amount to each phase for rotation angle, horizontal move and vertical move, respectively.  The % number need not to be same for rotation angle, horizontal move and vertical move.  By adjusting the ratio of each phase for three movement factors, finally you can acquire your own rod movement as a casting style, bingo!.

Registration of Casting Style (Save)

There is a feature to name and save the contents of specification in the definition window to database.  When ready, enter the name and press [Register the Window] button.  When the same name already exists, a message prompts.

Update, Deletion of the casting style entry

To change the contents of definitions and save it with the same name, user must invoke the entry, modify the definition, delete the entry and save the contents with the same name again.  This series of operation can be performed on the same panel in sequence.

When completing the definition or modification, press [View/Delete Casting] button.
Pop window shows up with a list of existing entries.  Click the name to be deleted then triangle record selector mark will move to the raw.  Click the same line by right button of you mouse and select delete or cut.  You may be prompted by Access to make sure the deletion.  Press OK will delete the entry.  Close the window.

Return to this panel.  Enter the same name and press [Register the Window] button to save the definition.

Function Buttons

Name Function
toggle unit switches the unit between feet and meter
View Casting Style by Graph shows Casting Style graph according to the definition in the window
Register the Window saves the definition in the window with the specified name.  The saved definition can be invoked by the assigned name. The same name as invoked is also acceptable.
View / Delete Casting shows pop window with a list of casting style entries.
To delete, press right button of mouse on the line to be deleted and select delete or cut.
Right after delete or save, this window needs to be refreshed to display the latest status.  To refresh the window, click right button of the mouse on the list and select [release sort/filter].
Return to Archive returns to Archive screen

Data on the screen

Item Meaning
Tip Top Velocity velocity of tip top in the respective Phase (distance/time)
Tip Top Acceleration acceleration of tip top in the respective Phase (velocity/time)
Tip Top G equivalent G in the respective Phase 
(acceleration / gravity acceleration)
Total columns shows the total of value from Phase 1 to 4.  Should be equal to Total Amount.
Total of Tip Top G equivalent 
(in red circle)
shows the total of added acceleration by each Phase.  This G represent the added acceleration in phase. (*1)

(*1) Added acceleration

The movement with no additional acceleration is called, equal velocity movement.  In this case, a rod would not deflect any further.  To make a rod deflected, the rod needs always to be accelerated additionally somehow in the movement.  This is same to the actual world.

To assure this, look at the G equivalent field (bottom raw) and make sure that the G value of each Phase is larger than the G value in the previous Phase.  For Phase 1, previous phase is zero G acceleration which means that the rod is not moving (as waiting for cast).   So we watch the Total of Tip Top G and try to make the number nearly equal to 4.0 in order to compare the deflection with the result of [Deflection/Stress] calculation where the calculation is assumed as "Translated" rod movement.

User needs to change the allocation of total amount to each phase for either of time duration, rotation angle, horizontal grip movement, vertical grip movement for this purpose.
