Drawing a New Moulding
Scan the moulding sample(if no wood sample is available skip to “Open a turbo-cad window”).
Take the moulding and slice a narrow strip so that it can be scanned on flat bed scanner.
Scan it and save it as a JPG Photo/file and import to computer desk top, name/label it with work order number.
Open a turbo-cad window.
In the Turbo-CAD Program > Select “New” in pop-up window > Select/click the white paper in top left corner(new)> Select “new from templet” > Select “GM Profile”, click “OK”> Go to the Model Space.
Select Tools at top of model space > drag cursor down to roster image and click Image manager> Click “NEW” in pop-up window> Look in desk top, or other location if no wood sample was provided, and select your JPEG image. Click “open”
In image manager, select/high light your file. Click “embed” on right hand side. Then click apply and then OK.
Select “Insert” at the top of model space, slide cursor down to “Picture” then click “from image list”. Select/high light your file. Click “insert”.
Attention! At the lower left hand corner instructions are given, “define the first corner of the image”. Note…just above this are two blocks that will indicate the width and hight of the file inserted.
Place the cursor in the model space, depress the left mouse key and drag the mouse until the desired width and hight are achieved, release mouse key. Suggestion, 8.5 and 11in. is the size of a sheet of printer paper. This will help when resizing the jpeg being inserted.
At this point, or any other point in the process you will want to select “file” at the top and “save as” and save your file to prevent accidental deletion of your work.
Resizing your insert to final moulding size.
Level profile image; use the line tool to high light /define the bottom most horizontal portion of the design. Use the T/C tools to “level off” the image on the insert to horizontal position. Note, this may leave the over-all insert in a non-level position. This is acceptable.
Establish current dimensions of image on file inserted, use line tool in T/C to make a “box” around the image on the insert. Make lines to define width and hight of image.
Use “no snap” and “orthogonal” tools in T/C together to get digital width and hight of the box.
To resize your image you have two options: With wood sample or without.
If you have a wood sample your target size will be what the actual dimensions of the sample are. Example, .7251 x 3.2214, not 3/4 x 3-1/4. if you are working with an electronic copy or a sketch then your target size will be the requested size from the file/customer, example 3/4 x 3-1/4 in digital format. Attention! The hight of the box is the “Y” scale the width of the box is the “X” scale.
Use the cursor and the “select” tool and high light the entire insert with the box. Attention! Divide the target value by the measured value of the box. Do this for the X and Y scales. Do one at a time. Note, Divide the target Y by the measured Y, then type the result into the “Y scale” block in the lower left corner of the screen. Then click “enter”. Repeat this for the X option. The result should be that the size of the box on the screen is exactly what the target value is.
Trace the Image of the profile/moulding.
Use turbo-cad tools to define the shape of the image. Note, the outline of the image may be blurry or thicker than the line established by the T/C tools. When possible, place T/C markings at the center of the blurred or thickened outline. This will best establish the original shape of the image.
Once the outline has been established, use the cursor and “select” tool to high light the shape of the image(only the image shape not the entire insert). Then copy and paste the image beside the insert in the model space. Remove any “service lines” and remeasure the moulding hight and width to verify the target value has been achieved.
Copy and paste moulding image, centered, in paper space(paper 1). In paper space, the moulding outline should be oriented to depict the “out feed” view. At this point, only display the hight and width dimensions in fractional format(degrees of slope optional for crown left and right sides). Rename the “paper 1” tab as “customer”. Dimensions on image in customer tab should be in fractional format.
Create a “shop” drawing for Moulder Operator reference.
Place cursor over the “customer” tab at lower left hand side, “right” click the mouse and select “duplicate”. Right click on the duplicated tab and select “rename” and type the word “shop”.
Inside the shop paper space, reformat all dimensions, except degrees of slope on crowns, to decimal form out to four decimal places. Example; .7251 x 3.2214. Also, add wood axial for both the top head knife and the back relief knife if used and add degrees of slope for crowns.
Add “fence bottom with arrow” image to shop tab in paper space to indicate proper image orientation. Out Feed View.
Save work, rename T/C file to show “GM” number.
Draw the knives
Draw the knives using the drawing on the model space.
Draw the knife 10mm (.394”) wider on each side, a total of 20mm wider than the moulding. A Minimum of 1.5 inch wide knife.
Overlap a 16th inch (.0625) when the knives need to overlap, for example on a round over.
The steel for the knife needs to be 1.5” plus the profile.
Draw the template
Using a copy of the knives for the template add 10mm (.394”) to each side of the knife. A Total of 20mm wider than the knife. And add .875” to the depth, (2.375” plus the profile).
Leave an 1/8th inch of the line from the Knife a 1/16th away from the end of the profile side on the fence side or the table side. ( for a mark lined up with the knife.) Write “GM000-T(for top head), -RV(for Right vertical head), or -LV (for left vertical head.) text size is .39” make it readable with the profile pointing up.
Save it as “GM#” in Moulding Library folder
SOP For Preparing Drawings to Order Knives and Templates from Hot Knives
Open a New file in Turbo CAD
Save a DXF file for each of the knives and templates
Select and Copy the knife or template and paste into the new file.
Flip the drawing horizontally for an infeed view. This is critical so the blade is sharpened the right way.
Save as > a DXF file > in the right job folder.
Create a file for each knife and each template.
Save an Infeed view of the moulding
Make sure the original Turbo Cad drawing is saved, and don’t save it after making the following changes.
Take the customer paper space, select the moulding and the measurements, and flip the moulding horizontally to make it an infeed view.
Delete the out feed symbol and replace it with the infeed symbol.
Print that page as a pdf, naming it with “infeed view” and save to the job folder.
Don’t save this when you close turbo Cad, since it needs to stay outfeed view.
Send an email to Hot Knives and copy Purchasing (Ervin) to order
In the heading include GM# and a PO# (which can be the work order #)
Attach the DXF files and the pdf Infeed view of the moulding.
Include a brief message stating to order it and request the approximate ship date.
Sop for Saving a PDF for the Customer/Sales Team.
Open turbo-cad file containing moulding image. Select the paper space tab labeled “customer”. Select printer icon in upper left corner. Use drop down option to select the printer option. Slide cursor down and select “PDF creator”.
