This places the work coordinate system exactly where it is supposed to be and the program runs properly using this (tool length value - Top of part MCS value) in a + form for G54 Z offset. I then put in a +5.0 and now things are exactly where they should be in Z. So I decided to try entering the value of (-17.1,tool length value) - (-12.1,MCS value the control showed for the work offset) = -5.0 into the G54 Z offset and this -5.0 is to low. When I try to run my program using G54(-12.1) I get a Z soft limit areas which indicates to me something is wrong with the offset. Just imagine a part in a vise 5' above the table hence the 5' difference in tool tip to table and tool tip to top of part in MCS values. I go to the Z offset location and press the yellow 'enter' key and it writes the MCS value of Z which is something like -12.1 to the Z offset table for G54. I have the offset set to G54 and T1 shows to be active. This is all under the jog screen under the 'Scratch' softkey function. I touch off on the top of the part just using a piece of paper as the feeler gauge. So I jog down to the top of my part that is clamped in a vice. I wanted to be able to just use T1 to be able to determine my G54 Z offset in the offset screen. I checked another drill in T2 and a shell mill in T3 in the same fashion and got similar values(something like -17.15 and -17.3) so everything still makes sense. The tip of the T1 tool touching the top of the machine table is '-17.1' in MCS. I changed the Reference value to 3(to adjust for the 3' height gauge under the tool tip) and did calculate again and it gave me a -17.1 in the tool offset. Here I hit Calculate softkey and it gave me a Tool Offset of -14.1(rounded decimal points off for simplicity). I hit the Determine Offset(think this was the wording of it.not currently in front of machine) softkey. I went into Parameters->Tool Offsets and on T1 I jogged the tip of the tool down to the table of the machine and used a 3' height gauge to position against table. Here is an explanation of what I have done(kinda long but wanted to provide enough details to understand what I HAVE tried): I have successfully wrote a working program and understand most everything, but I am missing something when it comes to the Tool Offsets and how they work with setting your work offsets. **edit - Just an FYI, this is on a 3-axis vertical mill** We are working on a Sinumerik 840D/MMC - 103 control from around 2002. Employment Opportunity / RFQ (Request for Quote).I am completely new to Sinumerik controls.The problem appear when use for G1/4 or onother G(gas thread ). N550 HOLES2(0,0,680,0,36,10) 10 X GAURI DE FI 8 G1/4 - LARGIT LA 11.5Īnd the alarm was the 'MPIT' parameter (13.16) it is not correlate with 'PIT' parameter (1.337)īut, for example when use this cycle84 for M6 or M12 or M4 or M30.

It is possible make a thread G1/4 with this cycle, cycle84 ? If it is possible can say me, how ? Because I try use this cycle but every time I had a errore about diametre and step thread. Somebody can help me with one information ?
