    Default What is H-Length?

    Hello, While entering the tool length info in solidcam, there is a field for 'H-Length'. The endmills I have did not come with any information on the H-length value, solidcam defaults to 100, so I left it alone. Anybody know what this is and its importance? Thanks, JSimilar Threads:

    Normally, H goes with a G43 in the Gcode. You should see: T02 M6 G43 H2 If there is no G43, H will have no effect.. H is the offset lenght of the tool Jeff

H is the offset lenght of the tool Jeff What jeff is referring to is the tool length offset command for CNC programing. G43 is the G-code to turn on the Tool length offset on most G-code machines (ex. Haas, Fanuc). The H number is the offset you want to use. When setup the tool at the CNC, Most Setup will use the same H# as Tool# to assign the tool length offset value on mills, but dose not have to match. Mill ex: T1 M6 (Change tool, 1/2 EM) G0 G54 G0 X.313 Y.313 S2400 M3 (position table, turn spindle on) G43 H1 Z1. M8 (This line will bring the tool 1. above the apart using tool offset #1) D is typical used for Tool Dia offset along with G41 (Left) or G42 (Right) Z.05 G1 Z-.25 F15. G41 D1 X-.01 Y0 F25. (Cutter Comp on) X1.0 Y-1.0 X0.0 Y.01 G40 X-.313 Y.313 (Cutter Comp off) G0 Z1. M9 G91 G28 G0 Z0 M5 (Bring Z axis to Home Position, Spindle off) M30 I just milled a 1" square, with part Zero being the upper left corner of the part. glovebox20

    Where H Length comes into play is when the user has set up Machine Simulation (or MachSim), especially in five axis machining. The value in H Length is the distance from the tool tip to the gauge line - if you have holders defined and are using them and you have specified the amount the tool projects from the holder in the topography page, H Length will show the combined value. Note that that this made up of the tool, the holder length and the toolholder flange (which is defined in a separate tab in holder definition). It takes a lot of work to set up but I wouldn't be without it.

    So is that only used during automatic tool change functions? I am not sure what the 'gauge line' is, I'm guessing it's where the collet holds the end-mill (such as a groove for it to lock on to).

    This is a small pic of where the gauge line is and what is tool length

No, it is nothing to do with automatic tool change but a lot to do with tool offset setting eg G43 calls. The Gauge Line is normally the spindle nose face and is the place where all tool length offsets are measured from (as shown in Jeffs's diagram). If you run your machines with the tool lengths defined in the program, H Length is variable that you would need to set (either manually or automatically) to output the necessary code (presuming that your post is set up to do that.

    We have an old milling machine with an indexing head that rotates 360 degrees around the "Y" axis. The controller is an old Heidenhain TNC 355 that only has one coordinate system and does not have any coordinate transformation/rotation functionality like the "cycle 19" on new Heidenhain controllers. We use the "H" length to allow tricky plane tilting. We have set-up our post processor to use the "H" length as the head pivot to tool tip length. We measure this length for all our tools we want to use, then manually load these values into the tool table in solidcam under the "H" length. This allows SolidCam to calculate the new X, Y, Z positions and generate the code to come out correct for each tool length based on the head rotation angle. It is a bit time consuming to set-up but it allows the machine to do things it would not normally be capable of! Jake T-B

    Wow seems pretty complex... how do I calculate H-length? Say I would like to get a value for my 10mm 4FL EM, 60mm OAL, 40mm Tool length, 25mm shoulder.

    It's not complex, but it is labour intensive if you want SolidCAM to calculate H-Length automatically. Basically, H-Length is the length of the toolholder sticking out of the spindle nose plus the length of the tool sticking out of the holder, nothing more. To set H-Length manually just tick the check box to the left of the H-Length value box and you can put whatever value you like in there. For SolidCAM to calculate it automatically you need to define (a) the toolholder flange adaption (MAS-BT, DIN, CAT, ANSI etc.) in Tool Holders (the upper box) and (b) the holder itself in the lower box. Then you have set the holder for all the tools in use. Oh, and you also have to set the flange adaption in the MAC file. As I said, it's a lot of work and unless you are using MachSim, it is a lot of work for little reward. I have machines here that have never been set up to use H-Length in posted G code - we set that on the machine via the tool offset table. If you need to set tool offsets via the CNC program then just set H-Length manually. To answer the question you posed about your Ø10 4fl endmill, you are missing two pieces of crucial information. What toolholder are proposing to use and how much is the tool sticking out of the holder?

    Only if you have access to Machine Simulation (the tab in your simulation dialog box) or your post processor uses this value to calculate positioning for 5 Axis head/head machines, should you care about the H-Length value - it does nothing for you otherwise!

    I do have a rotary axis I plan on using before not too long. I have to disconnect my X axis controller and plug into the rotary, so the rotary becomes my X axis. I have yet to try it out, I have not had time to get into it yet but really look forward to it. I'd like to make a few pool cues later this year. Would I need H-length for rotary operations?

    No, H-Length isn't required for rotary operations unless you were using Machine Simulation or your post processor was setup to do something funky!
