Amada - Edge and Approach Amada - Edge and Approach kltex (Industrial) (OP) 20 Dec 15 18:07 Can anyone help me solve the pazzle, Edge and Approach data When does each come into action? RE: Amada - Edge and Approach evans1089 (Mechanical) 21 Dec 15 09:11 I think its the corners and radius of edges. Usually they're used on thicker material, where the beam has to change direction. RE: Amada - Edge and Approach laserdog (Computer) 21 Dec 15 11:09 Approach is your lead-in line so whatever conditions you use will start after the pierce, edge data is used on corners. RE: Amada - Edge and Approach kltex (Industrial) (OP) 22 Dec 15 04:13 Thanks What about fine edge? RE: Amada - Edge and Approach 2 laserkatana (Mechanical) 28 Dec 15 21:20 Fine edge control is for high speed machining of thin materials (up to 10 GA or .135")with Nitrogen Assist Gas. Laser power is modulated according to acceleration/deceleration. Where acceleration power ramps up, deceleration power ramps down. In a nutshell it is to eliminate leaving burrs on corners or where a straight leadin meets the contour by reducing the power according to feedrate. Approach Data is to slow down after the pierce and stabilize the cut. Edge Data is used to pulse on corners specially while cutting thick plates with large diameter nozzles. This prevents the burning on corners by using low power, frequency and duty, as well as low speed. Both Approach and Edge Data are mainly used in thicker materials. Hope this helps RE: Amada - Edge and Approach ausman (Industrial) 11 Jan 16 08:04 well said, fine edge is tricky to work out as it did not seem to be much information in the manuals. The setting are in the fine edge data page push custom button then left arrow soft button then parameter then page down (seems like amada wanted to hide it) you can use 901 to 910 Turn it on in the the cutting data page under pulse type column. (you can select from 901 to 910) when you are cutting you can see that the power, freq & duty are changing when contouring. RE: Amada - Edge and Approach Fiberjerm2 (Industrial) 11 Jan 16 18:40 Does the Fine Edge Data include the holes or just corners? Apologize for the intrusion. RE: Amada - Edge and Approach evans1089 (Mechanical) 12 Jan 16 14:55 From experience, it depends on the size of the hole and thickess. You'll find a longer lead in and a radius with thicker materials RE: Amada - Edge and Approach sparky4808 (Agricultural) 12 Jan 16 21:38 @laserkatana I have a part that makes almost a 180* turn (picture the outline of a U)and always leaves my operator grinding out the burrs. you can see a definite hot spot on each corner. we are cutting 1/2" mild steel with the following condition: 38IPM, 3000w, 700hz, 75%duty. GP 0.07 oxygen. using 1.4 double nozzle. what would you say would be a good edge data to try, I can get anything to work out for me. RE: Amada - Edge and Approach laserdog (Computer) 18 Jan 16 18:12 Your heat issue can be many things so at this time more info would help. If your focus is off you can have this issue. If you run too slow for your cut conditions and heat up a larger surface area you will see this problem. What is the inside dimension of the U? All the 1/2 we cut is with 3800 power, 95% duty and 100 freq with a feed of 45-50 and a focus of -.079. But these lasers are 15 years old and things have changed in time so it may not even come close on the newer lasers.
