Flange Hole Marking Calculator is used to calculate flange hole marking of equi-spaced flange holes, flange holes at any Angle and to calculate maximum No. of holes can be marked on circle.

Flange hole calculator is very useful during hole center Marking on flange at a given Pitch Circle Diameter or Bolt Circle Diameter. This calculator gives hows much cord length required to divide required No of hole on our available Pitch Circle Diameter or Bolt Circle Diameters.

Flange Pitch Circle Diameter (PCD) is noting but the diameter along bolt hole center. It is denoted by (PCD). This diameter is also called as Bolt Center Diameter (BCD). It is very important parameter while diving flange hole. You can refere for standard reference drawing to understand this dimension to provide correct input values. You can use any dimentional units such as Inches or MM as per your prefererance. if you are using Inches as units for your input values then please refer decimal fractional chart to enter proper input values.

No. of Hole (N) is noting but how many holes we want mark on available flange pitch circle diameter or bolt center diameter. it denoted by N. It can be any no. of holes as per your flnage configuration.You can refere for standard reference drawing to understand this dimension to provide correct input values.

Flange hole angle is nothing but angle on which this flange hole to be going to mark. it denoted by θ. This angle should be enter in to degrees. This angle is depends upons location of you hole on pitch circle diameter or bolt circle diameter with respective to your selectyed plane.You can refere for standard reference drawing to understand this dimension to provide correct input values.

Circle Diameter (D) is used only while calculating maximum no. of equivalent hole can be fitted inside circle at equal distance or equal pitch. Circle diameter is refered in this calculator as Outer Diameter of Circle on which we want to calculate maximum no. of small diameter holes can be available to mark. You can refere for standard reference drawing to understand this dimension to provide correct input values. You can use any dimentional units such as Inches or MM as per your prefererance. if you are using Inches as units for your input values then please refer decimal fractional chart to enter proper input values.

Hole Diameter (d) is nothing but the diameter of Hole that going to mark inside outer circle while calculating equivalent no. of holes. It is denoted by d. You can refere for standard reference drawing to understand this dimension to provide correct input values. You can use any dimentional units such as Inches or MM as per your prefererance. if you are using Inches as units for your input values then please refer decimal fractional chart to enter proper input values.

Hole Marking Distance (C) is calcuated by this calculator using your input values. Hole Marking Distance is required to Mark hole on Pitch circle diameter or Bolt circle diameter. It very useful dimension to locate hole on flange. this values can be calculated according to your input units selection.
