## Indexing calculation in milling

Turn your INDEX G220, INDEX R200 or INDEX R300 turn-mill center into a gear on the machine control; On request, calculation of parameter data by INDEX  Take for instance a crank with 100 divisions and with calculator, divide by 9 on the index plate and any subsequent work that is indexed during machining will

## used for milling circles, angular indexing, arcs, segments, circular slots, grooves calculations similar to those used in calculating change gear ratio for lathe

Covers the use of the dividing head. Covers plain, differential, and angular indexing. The course explains the use of the dividing head for milling hexagons. This online course proceeds to the cutting of spur gears, helical gears, and cams. Indexed Milling Procedures is available in online technical training and course manual formats. TPC Training is authorized by IACET to offer 0.5 CEUs for Indexing or dividing_head 1. The Indexing orDividing HeadSession 14 1 2. Indexing (Dividing) Head• Once one of the more important attachments for milling machine• Used to divide circumference of workpiece into equally spaced divisions when milling gear teeth, squares, hexagons, and octagons• Also used to rotate workpiece at predetermined ratio to table feed rate 2 UNIT 1 MILLING Milling Structure 1.1 Introduction Objectives 1.2 Types of Milling Machines 1.3 Working Principle of Milling Machine 1.4 Special type Milling Machines 1.5 Principle Parts of a Milling Machine 1.6 Specification of Milling Machines 1.7 Cutting Parameters 1.8 Milling Cutters 1.9 Milling Machine Operations 1.10 Indexing （Problem） What is the cutting time required for finishing 100mm width and 300mm length surface of a cast iron (JIS FC200) block when the cutter diameter is ø200mm, the number of inserts is 16, the cutting speed is 125m/min, and feed per tooth is 0.25mm. Using Dividing Plates with the Rotary Table Dividing plates allow you to precisely divide a circle into a number of divisions or degrees. The indexing feature helps prevent errors during the repetitive adjustments required in indexing work. Dividing plates can be used to create bolt circles, gears, polygons, and so on.

Milling Equations Machining Time : Peripheral Milling T m = L + A f r T m = Machining Time (Min.) L = Length of Cut A = Approach Distance f r = Feed Rate (Dist./ Min.) Machining Time : Face Milling T m = f r The calculation to determine 13 1/2° when an. index plate with an 18-hole circle is available, is as. follows: or 2 holes on the 20-hole circle. COMPOUND INDEXING. Compound indexing is a combination of two plain. or one complete turn plus 9 holes on the 18-hole. indexing procedures. You will index one number of.
