Tech Tip: Diameter and Degree Symbols in Drafting Notes
Webby replied to Webby's topic in Industrial Forum
In V8 under Drafting Notes, you'll be able to pick from a dialog box. For the actually Alt Codes, start numbering the top row at 32. The second row starts at 48. For example, to output the +/- symbol in V7, the bottom row starts at 240. The number is then 241 for the +/- symbol. Under Drafting Notes, type [Alt+0241] to get the +/- symbol. -
If your square block boss had no draft angle, or if the bore axis was 90deg to the drafted face, you would be fine. The angle between the bore and the boss face must be constant. I tested this in other Parasolid-based modeller, and was able to chamfer your part without these constraints. I'll pass this along to CNC Software.

The release date for Mastercam V8 is Tuesday, May 30.

Here's the Mpfan (Fanuc) post from the V7.0 CD: http://www.emastercam.com/posts/ftp/mpfan_70.zip

In V7, Highfeed is 'toolpath filter' C-Hook, only acting on the ASCII NCI file. In V8, the Highfeed button is right in the Operations Manager. Highfeed works on the Binary toolpath directly in the Operations Manager. After the 'Highfeed' treatment, operations are locked so that Regeneration does not automatically restore a toolpath to its calculated state, without feedrate optimization.

It looks like the release date for Mastercam V8 is Tuesday, May 30.

Due to the addition of Mastercam Solids, and the change to Sirius NC Verify for verification, no on-line updates are available to jump to v7.2 from earlier versions. The file sizes would be very large. Ask you reseller for a v7.2c CD! The patches that are available are found under the Information section (formerly 411) of this web site.

Your reseller reports things are sorted out.

Traditionally Wire lags by about 3 months behind the release of Design/Mill/Lathe. Looks like end of Q3 and into Q4 based on that rule of thumb - but again - there is no official release date for any of the V8 products.

Brad Eyben wrote: "Anybody using old machinery that is only 2 axis simultanius and if so how do you deal with x,y,z moves that the program likes to dish out?" -- The moves can be split up in the post - but this method is very coarse at best. I would limit the number of axes used by selecting appropriate toolpaths in Mastercam. For instance pocket roughing and contour finishing for Z and XY only moves. If XZ and YZ are valid 2-Axis combinations, you use finish parallel at 0deg and 90deg.

If you mean how do you prevent the dimensions from overlapping, try using the Adim C-Hook. It uses segmented leaders to prevent dimension overlaps. Any other thoughts out there?

V8 is in its final beta testing release. Once feedback from the beta release is compiled and addressed, the production release CDs will be manufactured. CNC Software does not have a date set for the final release at this time. When a date is set, I will post it to the forum.

MODIFY-SURFACE-TRIM-FLAT BNDY and MODIFY-SURFACE-TRIM-TO CURVES are both available as functions in V8. MODIFY-SURFACE-TRIM is available as a function in V7 - hit F10 for a complete list. This means you can create an Icon or a Hot Key for the function. Looking for these under CREATE-SURFACE-TRIM is a no-go. The function is double-listed in the Mastercam menu structure, but only has one true name. Write up a detailed description of where "Window" doesn't behave how you would expect - email to me - and I'll forward it to QC.

V8 has a C-Hook named Align that lines up Dimension Notes, but dimensions themselves haven't been included. I'll pass this along to QC.

Please respond this week if you have an opinion on V8 default settings: Job Setup -- Assign Tool Numbers Sequentially is On - Is that OK? Yes or No Tool Offset Registers has a default value of 40 - Is that OK? Yes or No Should it be 0 instead of 40? Communications -- Set parameters from PST (q80 -89) this is on by default - Is that OK? Yes or No Other -- Comment on any other default settings from v7 that should be changed by default in v8.

Your reseller has been contacted to help sort out your post issues.

To lead in and out when using the constant Z 'Surface/Finish/Contour' toolpath AND keep the entry point from gradually moving around your workpiece, use a Tangential arc angle of 180.0 under Gap settings. Moving the entry/exit point around the part with not leave a witness mark, but the motion is obviously less predictable.

Drawing 3D wireframe allows you to use the "Incremental 0" depth setting method, where the geomtry itself sets the cutting depth. This method is also well suited to associative updating of design changes, and the setting up of operation libraries that can be applied to different parts.
-
To make things easy, if you are building a single object, it should be a single solid. If you have two objects, they should be two solids. You may want to chamfer or fillet an edge of an actual object, but you don't fillet the intersection edge of two objects. The only acception is found when you are creating intermediate solids to use in Boolean operations.

C-Hook Source Code
Webby replied to PBoulanger's topic in Mastercam C-Hook, NET-Hook and VBScript Development
One or two of the simple C-Hooks are included in the C-Hook Developer's kit. Other than that, they are unavailable -including the Setup Sheet C-Hook source. The 'reamer as a tap' and tool material issues are addressed in V8. We do have the ability to customize the HTML Setup sheets found on the eMastercam 'Tools' page, and do so at an hourly rate. -
You can insert extended character set symbols into Drafting Notes by holding down the Alt key and typing in numbers. Release the Alt key and character will appear. Two helpful characters: Diameter: í [Alt+0237] Degree: ø [Alt+0248] These will appear as the correct symbols in Mastercam. Watch for complete re-write of Drafting in the upcoming V8 release.

Mastercam will import Parasolid files (x_t) as solids, and V8 will import Cadkey ACIS files (SAT) as solids as well (converting to Parasolid on the way). V7 handles the SAT files as surfaces. Mastercam uses the Parasolid kernel so x_t files are preferred. With all solid files, you can import a wireframe at the same time, and convert solids to surfaces, so all geometry entities are covered. I encourage others who use both systems to reply.

The March 2000 Modern Machine Shop featured an article on Tool Measurement. You can visit the MMS Online Calibration page at: http://www.mmsonline.com/measurement/calibration.html The "Don't Touch That Tool" article is from the March 2000 edition.

The C-Hook is called Thelix. It creates a helix as a parametric spline with center at X0Y0. You would then have to create a surface (or solid) using a cross section swept along the spline. The Spiral C-Hook could also be potentially used. The inputs are slightly different, but it creates one spline per revolution, rather than one spline for the entire helix.

Brad's method is correct. Swept solids are fairly taxing on the system. Many solid modellers actually have options to suppress threads in assembly views to lessen the heavy load on the system memory.
