You will need callipers (+/-0.05mm) and an accurate rule The setting of the V notch blades on a ZX3 Ring revolves around the setting of two groups of parameters: *V and W axis positions *Blade offsets for each blade The rough position of V and W axes is set first, then the individual blade offsets are set, and finally a test is run to tweak the accuracy to gain perfection. There are two “tweaking” parameters for each blade. The two parameters are: *Depth offset – how deep into the bar *X axis offset – position of point of blade relative to the spindle centreline false en TM018B_Microline_and_ZX3_V_Notch_Blade_Setup_ZX3_Ring.jpg none A calibration mnd file has been written to help line up the  x offsets called VTEST. This program creates the following pattern on the bottom of the profile using a 10mm spindle and the notching blades themselves: Run the VTest operation on a length of large outer frame of at least 1m long. Put the    operation at a position of 500mm. The pattern allows you to measure the offsets required with calipers. <br/><div class="icon-instructions info-icon"> <div class="icon-instructions-icon"><i class="fa fa-info-circle"></i></div> <div class="icon-instructions-text">...Profile is viewed from the bottom face, Basically turn it over when it comes of the transfer table.</div> </div><br/> # Measure between the VI blade and the edge of the 10mm slot – This value is the xoffsetVI (and also the xoffsetWI).  (We need to add 5mm to the measured Value).

Find out which V Notch files the machine is using by checking the operation setup. A simple way of doing this is shown in the pictures by starting a "Manual Input". Picture 1 - shows this machine uses VF / VR codes Picture 2 - shows a different machine using VAF3 codes Note this "mnd type" for later <div class="icon-instructions info-icon"> <div class="icon-instructions-icon"><i class="fa fa-info-circle"></i></div> <div class="icon-instructions-text">...The VF... codes are the original method of setting up the machines, the VAF3 codes are seen as an improvement because it makes the naming of the variables for the offsets a little clearer and groups them together. It also improves the machine cycle time by allowing the use of startOffset - the x axis needs to move only once to the start of the V notch</div> </div><br/> #Set the xOffsetVI and WI to the new value settings. THIS VALUE IS ALWAYS POSITIVE #Set the xOffsetVO and WO to the new value in settings. THIS VALUE IS ALWAYS NEGATIVE Depending on the software version, there are 4 places where these settings are stored / edited Before You Start Run a VTest Measure Results for x Offsets Update the Parameters for xOffsets Microline ZX3 VNotch Setup Blade bladeoffset 2019-10-23T09:20:56Z 2458779.889537 TM018B Microline and ZX3 V Notch Blade Setup 0 false false 0 0 0 0 plainlist 1 [[:Item:150mm Caliper]] TM018B Microline and ZX3 V Notch Blade Setup# QUERY4813e830db1d5bf9f610863617904738 0 0 plainlist 1 [[:Item:150mm Rule]] TM018B Microline and ZX3 V Notch Blade Setup# QUERYca16dbbc61f83f95fd87d45e2cab38d4 0 1 plainlist 3 [[:Dokit:DocOptions]] [[DokitEPIEnable::yes]] TM018B Microline and ZX3 V Notch Blade Setup# QUERYee7a61aae48f1c3f91d8e4d7736360be
