depth of cut issues

Post by ccamfield.ch6 » Wed 22 Jan , 2014 13:10 pm

I have a mrc 40 / compact 1000.

I am a dt technician and our IT technician has produced a program to cut out some shapes.

I have the machine set to metric. The board we use is 6mm thick

IT guy says he has asked it to cut 1.5mm each time over a thickness of 6mm. so 1.5 3.0 4.5 6.0 pass until it is all cut out.

What the machine is actually doing is 1.5 2.0 3.0 2.0 4.5 2.0 6.0. so not always cutting just moving around.

is this something anyone else has encountered? machine error ? human error?

any help would be great as it would certain speed it up a bit

What software are you using to create the machine file?

If it's a 2D file then you just need to set the step down percentage to suit the tool. if it is a 6mm cutter then a 25% would be 1.5mmm per pass.

Reply from our IT guy

Hi Chris,



I used the Denford VR Milling V5 software from a 2D DXF file. The initial cuts were at 1mm per pass, it just seems to repeat sections or add in extra steps not initially programmed.

IE 6 steps starting at 1mm – 6mm (depth of MDF) but its doing something more like 12 passes but in a random order.



My last test was doing something like this pattern



Pass1 – 1mm

Pass2 – 2mm

Pass3 - 1mm

Pass4 – 3mm

Pass5 – 2.5mm



And so on with seemingly no pattern.
