Sometimes when the tool goes past the vertical it will double cut that area

Try this

Since the geometry is an arc set the tool axis control to a point and choose the center of the arc

depending on the tolerances required - just offsetting the curves in z does not

scale the radii and will give some variation from the intended part

but offsetting the surfaces scales the curvature in the z direction

if offsetting the curve keep the offset to a minimum

Could not make surface contour work on this geometry

Tried verything I could think of - new curves - new geometry etc

It did work by offsetting the drive surface - creating an edge curve

on this surface and then using a swarf toolpath with chaining set to sync by entity

Try this method to layout a cone

CONE LAYOUT.MCX-5

create a sillhouette boundry around the features

and offset the boundry by the distance needed

You can also use autodrill to automatically create drill toolpaths

here also the geometry has to be drawn correctly

+ 1 on the stl compare to prevent errors

Ellipses and parabolas are different geometry

there is a c-hook "fplot" that allows you to plot equations

Machinerys handbook or the internet will give you the equation

Maybe backplot the theads you have

then save as geometry to find the start point

If there is a solid put edge curves on that

Otherwise create curve all edges only on surfaces that that do not share an edge

then go back and create curve one edge on the remaaining edges

Strange that running a contour and saving the backplot as geometry

didnt help - that technique seems to work well

waht filter toleance did you use

In the opeations manager choose select then set the parameters to use

all opertions using those criteria will be checked in the operations list

in this all toolptah using the selected goemetry

Use the arrow at the top of the selection window and pick the holes

in the order wanted

Not that familiar with SW but if you can

create concentric circls projeted onto the

geometry you could use a series of contour cuts

Create a contour toolpapth with cutter comp off

filter the toolpath and save the backplot as geometry

create line tangent to the arcs

Try this

Cut one way

cut both sides

no z follow motion

gap setting optimize

Try this

Cutting "one way"

Cut both sides

No z motion up or down

gap setting optimize cut order

Thanks for reply

Company wants to do contract work for Boeing

and the understanding is iso 9000 certification is required

The info was Mcam certification was a requirment for certification

Perhaps this is a misunderstanding

I understand Boeing is requiring programmer certification to do work

for them - can anyone explain what this entails as far as documenation and

programming level - ie: surfaces - 5th axis etc.

Thanks for info

Thanks I'll post and look

RE: the previous post

Forgot to include

Using Mcam X5 MU1

Also many of the tool libraies included with

my install apear to be unreadable in X5

When using face drill on the sub spindle how

do I get the drill to oriennt to the right - toward the tailstock end

Thanks for any help
