V Notch, Ecoline ZX5_V_Notch_Blade_Mechanical_Setup_step4.JPG

Introduction

This is the full setup procedure for V notches on an Ecoline. This should only be needed on initial commissioning or if the shape of the notch has changed due to some physical intervention, for example -

- Blade Change

- Blade buckled

...If there is no direct reason to change the blade shape or position, there is a different root cause to the problem that changing parameters WILL NOT SOLVE

...If the results of your tests do not make sense, or the position seems to vary by the wrong amount or wrong direction after making a change, then a serious mechanical problem exists elsewhere. There is no sense carrying on because you cannot complete this setup unless the machine is consistent and reliable

Tutoriels prérequis

Ecoline - Datum and MitreOffset Tests

Étape 1 - Ensure the Datum and mitreOffset setup has been run

...Ensure that the ecoline is producing consistent and reliable datum test results

Étape 2 - Prepare Profiles

You will need several lengths of large outer frame, around 1m long with square end preps.

Étape 3 - Measure the bar width

Measure the bar width accurately with callipers

...The depth of a V notch is entirely dependent on the width of the bar. The machine must be set up with the bar width to calculate the notch depth correctly

Set the width of the sample profile in the flowops program to the nearest 0.1mm

Étape 4 - Separate the V notch to help measure

Starting with Front V notches (repeat this process later for rear V notches)

The distance between the V notch blades is known as the separation. This should be temporarily 'expanded' during testing to make the shapes easier to measure.

It is normally around 136-138, so add 10mm on to the existing parameter to make 146-148

...Separating a V notch like this also prevents a lump of the piece falling out which makes it weaker and therefore unsuitable to run through a second time

Étape 5 - Cut a V notch of around at a position of around 400mm

Use something around 30-40mm depth

Étape 6 - Measure and Adjust the Depths

The goal is to get both physical blade depths the same by tweaking the depth of the "outfeed" offset using the dOffsetVO.

The notches are named "infeed" and "outfeed" to standardise the notch cut on both left and right feed machines

VI - Front Infeed

VO - Front Outfeed

WI - Rear Infeed

WO - Rear Outfeed

Make the adjustment and run again to check

Étape 7 - Measure and Adjust the Separation

The goal is to reduce the separation back to a good overlap.

The simple way to do this is to measure the 'expanded' separation distance and subtract this from the VSEPERATION parameter

Make the adjustment and run again to check

Étape 8 - Set V notch Depth

Now that the shape of the V notch is correct, adjust the overall depth.

IF this is the "first time "setup on the front V notches, the V axis datum should be changed to ensure the machine is set in the correct base position.

IF you are tweaking the values, use VSTARTPOS and WSTARTPOS adjustments:

Front V Notch

Use the VSTARTPOS parameter

Increasing the VSTARTPOS parameter will make the front notch shallower

Rear V Notch

Use the WSTARTPOS parameter

Increasing the WSTARTPOS parameter will make the rear notch deeper

Make the adjustment and run again to check

...The VSTARTPOS and WSTARTPOS parameters are only displayed on the Notching tab on later software versions - if they do not exist, they need to be edited in userVariables.mul and this requires a reboot

Étape 9 - Repeat the depth settings for the rear

Repeat from step 4 for the rear notches

Étape 10 - Check and adjust alignment of V notches to datum holes

Run a piece with a datum test and V notch in same position

The goal is to align the hole centreline and notch centreline precisely

Adjust the xOffsetVI parameter to tweak the position (xOffsetWI for rears)

Make the adjustment and run again to check

Repeat for rears

Étape 11 - Back to back check

This test is an in-depth test to ensure all parameters are working together

1. Cut two clean pieces of outerframe
2. Measure their length with a trusted tape rule to nearest 0.25mm
3. Create two pieces with a V notch in the centre of the piece (needs to be to nearest 0.1mm)
4. Compare back to back to ensure all parameters are set up correctly

...If there is any misalignment at this point, a small amount (<1mm) can be removed by tweaking the xOffsetVI. Any bigger than this means there is another root cause
