move starting point to recut another part

[thereclinerman]

using mastercam x6 router with a thermwood single head router.



i am programming one half of a 4 x 8 sheet.  would like to cut the same pattern on the other half of the sheet in the same cutting cyle.



how would i cut the mirror image of the firt half . file shows the pattern.



thanks for any help.


thanks for all the help. copied and pasted all toolpaths. went into planes(wcs) and changed y by 24. problem solved.



sorry for not making it clear.



the 4 x 8 is a sheet of plywood laying flat on the router. i toolpath 1/2 of the sheet (2 x and it cuts entirely throught the wood  would like to cut the same toolpath on the other 2 x 8 side without flipping or having to create the the extra toolpaths.

I cant see the file but you could flip the part and rotate it so the plate is upside down depending on symmetry.

 

But I would xform mirror and put an moo in. Machine a couple indication holes or slots in the waste area to line it up.

The nesting toopath can do this, see,  Nesting Toolpaths on Both Sides of a Sheet in the help fiile

Nesting Toolpaths on Both Sides of a Sheet

Mastercam Nesting allows you to nest parts that have both front and backside toolpath operations. Toolpath operations such as dados and blind holes can be performed on one side of the sheet, and then the entire sheet can be flipped over to finish the parts prior to cutting them out. This flexibility can reduce expensive secondary operations without requiring changes in product design and construction methods. You can even nest parts that have only a single operation on the back side of a sheet (front-side operations are not required).

To use this feature, you must add the toolpaths to a nesting operation as a single cluster. If one or more of the toolpaths in a nested cluster have opposing tool plane views (such as TOP and BOTTOM) relative to the same WCS, Mastercam automatically creates separate nesting operations for each sheet. One nesting operation contains all of the front-side toolpaths (TOP), and the other contains all of the back-side (BOTTOM) toolpaths.

A pair of nesting operations for the same sheet display in the Toolpaths Manager directly below their parent nesting operation. This is illustrated in the following picture. Mastercam adds "[BACK]" and "[FRONT]" to the Sheet number label. A similar suffix is added to the NC filename; "-B" for back-side, and "-F" for front-side.

To nest parts that have operations on only the back side, add a single operation with a WCS=TOP and TPLANE / CPLANE=BACK to produce one nesting operation ([BACK] only).

Based on the Stop Condition settings in the Toolpath Nesting Parameters tab, you can post the nesting results to separate NC files (Stop Condition is None), or to a single NC file (Stop Condition is Stop or Optional Stop). When posting to a single NC file, Mastercam inserts a stop code between the front- and back-side operations so that you can flip the sheet.

Use the following guidelines to set up double-sided nesting operations:

• Add toolpath operations with opposing tool planes as an operation cluster to enable double-sided nesting operations.
• Mastercam assumes that you will flip the sheet along the X-axis and against the Y-axis. If this is not true for your application, you must modify the post accordingly.

• When working with 3D parts, the Tplane origin is used to represent sheet thickness. Listed below is more information on how to use the Toolpath Coordinate System dialog box to correctly set up planes for your back-side operations

  If Z0 in the Working Coordinate System = the top of the spoil board (table):

  • Then for operations nested on the back of the sheet (Side 2), set Z in the Tplane / Cplane equal to the negative value of the sheet thickness.
  • For example, if you are using inch sheets, you would enter -0.25.

  If Z0 in the Working Coordinate System = the top of the part:

  • Then for operations nested on the back of the sheet (Side 2), set Z in the Tplane / Cplane equal to the positive value of the sheet thickness.
  • For example, if you are using inch sheets, you would enter 0.25.
