Pcd Calculator
NOTE: The calculator is incomplete and additional features will be added later on. Please report any bugs or erroneous results. The true position calculator is a tool to calculate the true position of the center axis after actual measured dimensional data is entered about a manufactured feature: either a hole or a shaft. It is compared to a theoretically exact target feature as described on a technical drawing document. Please note that not all possible combination of control frame features are supported by this calculator. The position control frame found on technical drawing documents are used to allocate an acceptable deviation to a hole or a shaft feature. One basic function of the true position tolerance is to prevent a component from forcing another component out of alignment at assembly time.
- Wheel and tyre fitment calculator - it calculates inset, poke, speedo error, tyre stretch and loads more.

How to Calculate PCD of Flange? How to Find PCD (Pitch Circle Diameter) of Four,Five, Six Hole Flange? Pitch Circle Diameter of Flange Calculation.
It takes into consideration the allowable deviation of sizes of the relevant features of an assembly. For example: a screw that binds multiple components together. The position control frame can also be seen as a way to ensure exact positioning, within acceptable deviation limits, of multiple components of an assembly. For example; dowel pins that slide into positioning holes. Recommended Usage Flow. Select the type of feature; hole or shaft.
Define the feature diameter basic size and deviation. Fill control frame data, positional diameter, boundary condition, whether the target is projected and the projected distance. Define the primary, secondary and tertiary datum plane label identifiers. Enter the target distances of the feature to the secondary and tertiary datum planes. Select the type of measurement type that is most appropriate. Enter the measured dimensional data. Compute all the data entered and evaluate results.
Target Feature Box. This section is where the type, size, position and deviation allowances of the feature are defined. Feature Type: Select the type of feature that will be evaluated. It can be a hole or a shaft.
Size of the feature: 3 ways are offered to define the minimum and maximum size of the feature. These values will affect the boundary condition of the positional tolerance. The bonus value if it applies. This is the where the actual measured size and position dimensions of the feature are entered. There are 3 ways to describe the actual size and position of the manufactured feature. 1- Basic position: - NOTE: All the dimensions are located on the primary datum plane.
A) The actual diameter of the feature b) The actual distance of the center of the feature to the secondary datum plane c) The actual distance of the center of the feature to the tertiary datum plane - NOTE: The projected distance is not considered. 2- Position and feature height - 2 sets of dimensions must be entered. The first set of measurements must be taken at the primary datum plane. The second set of dimension must be taken AT the 'feature height' distance from the primary datum. A) Feature height: The distance that the second set of measurements will be taken, and positional calculations will be applied or from which the calculated projected position will be evaluated. Measurements located on the primary datum plane. This is where all the calculated results are displayed.
They are filtered depending on a combination of the target control frame inputs and the type of measurements entered. Compute button: - Evaluate entered data and update results. Results are synced with controls: Yes/No ( IMPORTANT information ) - This gives a feedback on the state if the results that are showed. If the result displays a ' Yes'. This means that the calculated values displayed were calculated using the unmodified values in the input fields above.
If the result displays a ' No'. This means that the values in the input fields were modified. The results displayed shows values that were calculated using a prior set of input values. NOTE Projected position are only evaluated if the type of measurements input entered are. A) Position and Feature Height b) Position and Compensated Height The results are summarized in three different value sets.
Datum data ( this set of values is always displayed.) - Feature height data ( this set of values is not always displayed and can appear grayed out, and in such a case, are for reference only.) - Projected data ( this set of values only appears when a projected distance is selected in the target control frame.) -Datum data results a) Feature within tolerance: Yes/ No - Is the hole or shaft within tolerance. B) feature within position: Yes / No (Position + Bonus allowance) - Does the position of the center axis of the hole or shaft lie within the target position diameter including the bonus value if applicable. C) Tolerance bonus: decimal value / No bonus - Displays the amount of the bonus allowed or No bonus if not applicable. D) actual true position: decimal value - displays the actual diameter the center axis of the hole or shaft lies on. This is a deviation from perfect 0 ( zero) position. NOTE: (only displayed if Position and compensated height inputs were entered) e) calculated distance from primary datum plane f) calculated distance from secondary datum plane - Feature height data results: - same as 'Datum data' with the exception that the results are displayed in the reverse order. NOTE: values grayed out ( For reference only) - The values are grayed out when a Projected target position was evaluated.
These values were used to calculate the projected position. These values are not to be considered when evaluating a projected position and are for reference only. Projected data results: a) Projection height - displays the minimum height of the projected position value.

This is the same value that was entered in the target feature control frame. B) Projection within position: Yes/ No - Is the calculated position of the calculated projection within the target position and the bonus value (if applicable). C) Projection true position: decimal value - displays the actual diameter the center axis of the projected position lies on. This is a deviation from perfect 0 ( zero) position.
D) Calculated distance from primary datum plane e) Calculated distance from secondary datum plane Further explanation on this subject will be available at later date. Mechanical Drafting & 3D Modeling SIZE.
