Introduction

This dokit is to help with the use of a wire line to set alignment correctly on mechanical build up. Using a wire line correctly will ensure a very accurate straight line is achieved . Accuracy of + - 1 mm over any distance can be achieved using the following method. Using one incorrectly can also easily be done.!

The steps shown can be applied to all types of alignment , when you have a vertical face on components that require aligning.

Étape 1 - Identify Datum component and set line

Firstly, identify the two datums that are required to set the wire line to.

A wire line should be pulled tight and then anchored to give a wire line from the first and last component

Étape 2 - Add components

1 Add additional components that require aligning to datum components.

...It is vital that these do not touch the wire line in any place

Étape 3 - Adjust components

1 Move non datum components forwards towards the wire line.

It is imperative that none of these components contact the wire line, as this will give a false reading. The goal is to get the components being added as close to the wire line as possible, without actually physically touching the wire line

2 this is an example of incorrect use and the exaggerated affect of touching the wire line

Étape 4 - Quality check

Once the alignment has been completed, all added parts should be double checked on wire line clearance, to ensure all of the above criteria has been achieved
