tool length compensation H registers help

[muxster]

tool length compensation usage on dynapath delta 40 there is H registers how to use them in program? when i put the H01 H1 say in line 10 i get 133 format alarm, i want it to use it before line 12 any idea what is wrong. anyone have sample program using tool offsets and manual tool changes.
the program i have runs complete just trouble using tool length compensation.
thanks marc

How tool length compensation is activated on a DynaPath control depends on the machine tool it's been applied to. View your block N0010 in the Program mode (Mode 3) and see if the H variable is even available. If not, then the tool length activation is probably tied to the T code itself.

It would help to know what kind of machine this control is on and whether you're dealing with a tool changer or not.

[muxster]

this is a knee type chaveler/(brigdgeport style) mill manual tool change no Automatic tool changer. the way they were doing length comp was using the z offset in the E offset page. do you have a example program with the tool comp used

[jagardner4]

Tool length compensation is entered into the T code table. And since this is a manual mill with no tool changer, the T code is used to make the tool compensation active.

The Z axis offset you are referring to is in the fixture offset table and is associated with and activated by E code. I don't think this is what you are looking for.

Your example is fine. The T code (T1) in block N0010 is activating the first tool length compensation in the T table.

if i do not put a Z value in the E1 register the machine over travel (cause .100 clear plane and no tool length applied) although if i put a example -1.0 in the E Z offset register everything ok except i lost 1 inch of quill travel and what to do on the next tool.

do you have example program with tool length and tool changes?

[guru]

On our Dynapath Delta 20

T0101 means call tool#1 and offset#1
T0100 will cancel offset on tool#1

T0210 means call tool#2 and offset#10

[muxster]

thank you guru

i will try that T0101

if i want the machine at the end of the program to return to Z home just have G0T0100 this machine has an air driven motor to unlock the draw bar/release the tool holder i want to put the machine ready for tool change (on the hass/fadal i just put Z0H0 at the end.

and to apply cutter comp use G41D01 is this ok

[jagardner4]

1. On the control, press the "Mode Select" key, then "3". This will put you into the Program mode.
2. Now press "N", "0" and the "Enter" key. This will enter a sequence number.
3. Now press the "Event Type" key and "9". This will bring up the "M Function" event, where T codes are programmed.
4. Press "T", then "0", then "Enter". Note how many digits show up in the T code field. It will be either 2 or 4 digits. This is the number of digits the control is looking for.
5. Also note if there is an H field. I suspect there isn't. If the field doesn't exist, the control will always give you a 133 format fault when you try to program one. Also, if the H field doesn't exist, the tool length compensation is being activated by the T code.

[muxster]

doing the steps 1 ~5 the control has uses 2 digits for tool not 4 still, confused on apply tool length compensation in part program for the dynapath delta 40

[jagardner4]

Based on your answer, I must assume that the control has a T code table accessible in Mode 6. Each T code in the table will have a Z entry and a D entry. The Z entry is the tool length, the D entry is the tool diameter. Both values are activated when you execute the corresponding T code. The tool length is summed into the Z axis command. Tool diameter won't be used until you call for cutter diameter compensation.

Short version: Your tool length compensation is being called by a 2-digit T code.

[muxster]

i agree with your post but this is what is happening at the control (dynapath) i use hass and fadal vmc's daily and i can use T1 with any H offset example H1 H41

example 1

Z value in the (mode 6 ) H1 register = -1. i cycle start the program below machine over travel (cause .100 clear plane/safety and no tool length Applied/activated machine is ignoring any tool table H data)

example 2

Although if i put a example (mode 6 ) -1.0 in the E Z offset fixture register i cycle start program below everything runs ok but machine moves to -.900 (-1.0 E Z offset + .10 clear plane) and what to do on the next tool T2, T3 ect. as program has other tool changes.

can you copy and try this program in your machine if you get the same as i do in example 1, example 2 the tool tip Z0 is set on the top of the block?

do you need to setup a reference tool master that the other tools link to?
