A lot of people use Helicoils or other inserts which have fixed thread depths
I agree. My commpany has standard drill and tap depths. The designers do not want to use the hole command because they have to adjust the thread and tap depth everytime.
My company is in the same situation with drill and tap depths that have to be adjusted every time. This populates errors. The depth ratio used by PTC is not practical.
You can edit the *.hol files to match your company standards. That is what we did at a prior company.
We took the machine shop list of tap drill sizes and modified the *.hol files so they called out what the shop wanted for a tap drill.
You can also create a custom hole file for things like heli-coil inserts, pipe taps, etc.
Yeah, we have done that as well, but hole depth and thread depth are not options in the .hol files. PTC uses an equation to determine what the values are.
Christopher is correct, since PTC calculates the drill depth (3 x drill dia) it will not match our company stds and the tap depth calculates out incorrectly as well.
It will be very useful, to configure the "thread depth" and or "drill depth" in a .hol - File.We need it in our company with 1000 users.
having the ability to specify hole depth per fastener line, would be greatly beneficial in allowing the use of the hole tables to drive custom holes for custom fasteners and location components. any word/info on this topic from PTC?
It is super annoying that every user has to manually modify every single threaded fastener they create just to get the thread depth and (blind) hole depth to match our internal company standards. Please add two more columns. Make them optional if necessary for backwards compatibility.
Since the hole files are only read when a new hole is created, the added columns do not need to be optional.
Maybe make the default tap drill depth 3X the diameter and the thread depth 2X the diameter as the default values. These values should be in the units of the hole file, not a factor of the diameter. Each company can then edit the hole file for their 'normal' usage of any tap/drill size.
We base the tap drill depth off the thread pitch to minimize excess tap drill depth. For example: Drill Depth = Thread Depth + (Thread_Pitch * 5)
We also want any ratios applied to be driven of the basic diameter, not the tap drill diameter. Thread Depth = 2.5 X Basic Diameter
Instead of trying to find a new standard (that probably no one will agree on), the .hol file should simply allow companies to enter their own values for each row for thread depth and tap drill depth.
Using a coded ratio to "set" the hole depth very much pigeonholes you into a corner. It assumes that you will always have a hole that is "X" deep in relation to its "Diameter". Like at your company Tom, we have custom holes that we need to produce nearly as often as we do "normal" holes. For example, we use a lot of "centering sleeves" which do not have a set height to diameter ratio. We have to manually adjust all of our sleeve receiving holes to meet the proper depth. Being able to dictate the drilled depth of the hole, via a tabulated value in the .hol file would greatly reduce errors, and time spent manually adjusting hole depths to match a specified application. We had been using UDF's to install these features, instead of the hole tables, but we found hole tables to be more stable between Creo versions. (Several of our UDF's broke when we updated from C4 to C7, and broke again when we tested on C8 & C9)Custom columns can be added to the .hol files, they just need to be at the end (far right/east side) of the .hol table. These columns are not able to be read by the hole tool to configure a hole, but you are able to use these columns in your notes. We use custom columns to add information to the callout based on the hole we installed.
.hol files are read only, however you are able to adjust the hole shape/size, as well as the diameter if you set the "hole_diameter_override" option to "yes" in your config
