3D machining - milling and engraving

For 3D modeling are designed so-called "CAD" programs. Most of them are absurdly expensive, but there are also those that are just and reasonable prices, thus we will pay.

This is the first description - I sent it to Mr. Machálek - is the author of this description and návodu.Tutorial 3D solid:

programs:

- CadKey99 (with FastSOLID99)

- OneCNC_MillProfessional 2000

- Mach 3 Version D1.90.065 registration with the club

1) Creation of the body (do not describe in detail, because otherwise every form element (AutoCad, 3Dmax ....)

The creation of the body I used Cad Key99, but you can use other programs to export objects in STEP format (. Stp). Alternatively, directly create OneCNC body directly, but I used to CadKey99

The Cad Key I drew a circumferential body dimensions and the layout exported in DXF file.

Ground body

Then I finished the body with FastSolid that I exported to a format Step (. Stp).

2) Creating paths for milling in OneCNC

When the program is necessary for correct assembly of G-code in the first set NC NC setup to configure the type and other necessary information. This does not describe it yet because I swim and I solved this style of trial and error, but for normal / we just use the default settings.

Now import element in STP format. Area should be divided into other grids, unless it is imported, we only circuit lines and for our case is useless (to me it happened when importing from DXF files.).

After importing the whole body is marked and press.

We will run out the following dialogue:

TOOLPATH - toolpath

Planar Routing - face milling in layers

Planar Finishing - slabbing final

Z-level routing - routing layers in the Z axis

Z-level finishing - final milling in layers in the Z axis

Denote the planar routing and we'll start.

SELECT TOOL - Choice of instruments

Length offset - offset length

Diameter offset - the average compensation

Feed rate along - feedrate

Plunge feed rate - rate of nesting tools (in Z)

Spindle speed - speed tools

Here is the tool used and offset parameters. Or change the feed rate and speed tools.

Clearance - Ground clearance

Rapid Z plane - Height retract

Plunge clearance - the movement of the tool material

Retract speed - sliding ryclost

Rapid - fast

Feed - supply (as in the previous table.)

Fill in the dialog exits and levels of material transfer tools.

Planar Cut Options - Set a planar milling

Toolpath angle - angle of the tool path

Zigzag min clearance - handle clearance

Leave for finish - leave before the end

Surface tolerance - tolerance of surface

Delphi of cut - the removal depth

Step over - setting step

Constant stepover - a constant step

Maximum stepover - maximum step

Scalop height - the height of milled

You adjust the angle of movement of machines, the minimum amount of milling, tolerance machined surface, the depth of a removal action and tolerance.

Boundary setup - Setting boundaries

Pick a Boundary - boundary selection

Aspire Box - block area

Part boundary - part of the

You choose the routing boundaries. Me, I choose to limit over time the body. A subsequent completion (circumcision) doing other G-code.

Cut boundary - boundary milling

The offset - offset from the axis

Calkulate of values ​​- values ​​calculated from

From the Top of Job - upper milling

From the Botton of Job - the bottom of the milling

You set the height offset and height dimensions of the material. After we finish the hammer to simulate end-milling path.

This asks us whether we want another tool path according to previous routing depth to a depth of cut. Let's do.

This is how it looks after the generation of all paths.

To calculate the total milling time select

To view the body (as some will look after routing results), this icon

Setting startup tools, body dimensions and parameters of the instrument. Just to see - the G-code is not that significant. But nice to look at it .. J

But it probably looks like this ....

Save the whole project by clicking on this icon to. tap.

The next stage is the final cutting element. We start a new file and importing of DXF layout.

Then click on the icon , click yes(whether we want to mill all the visible lines)

You fill the oppressed offset offsets Length: 0, offset Diameter: according to the tool radius, then turn the speed milling and feed, eventually. speed and spindle speed.

Again, fill the necessary information on the movement of the tool (preferably as in the previous case), including one deep rytíJ removal.

And we finish. Here you can try and shape processing time ...

A re-save the project by clicking on this icon , Of course, under a different name, but the format. tap

3) Routing in Mach3

Just short.

Set cutter (physically) to zero for future housing.

With ref all home and reset the software reset axis axis

Play into the first G-code and after some time milled rugged area of ​​the body

Play into the next G-code in body contour. Software may not change the zero point without changing the physical! A re-milled.

And it looks like the routing

Note.: This mill body in other ways, but not inclined - are inclined this way is very time consuming and the quality of design slant.
