EDGECAM Turning
EDGECAM Turning provides functionality for a wide range of machine tools, including
2-Axis lathes, multi-turret configurations, sub-spindle turning centres and mill/turn
machines. On a mill/turn machine, C-, Y- and B-Axis milling, and drilling take place
within the same program as the turning to provide a fully integrated and associative
programming solution.
Edgecam fully supports all axis configurations from the most basic 2 axis turning centre,
right through to a CYB multi turret sub spindle Mill / Turn.
Features at a glance:
- Increase machine tool utilisation
- Reduced programming time
- Reduce component cycle time
- Eliminate programming errors and reduce potential scrap
- Reduce machine tool prove out by graphically simulating the tool path
- Avoid collisions and expensive damage to machine tool
- Full support for canned cycles
- Reduce tooling inventory and stock
Edgecam produces advanced rough and finish turning cycles, together with support for
facing, boring and drilling in either canned cycle or longhand format. Toolpath
calculation takes into consideration the complete tooling insert and tool Holder including
the ''F'' distance and previously machined material to avoid gouging and eliminate air
cutting. Ease of use and an understanding that cycle times are critical, especially on
multi-configuration mill/turn machines, underpin the development of Edgecam's turning
functionality. Edgecam offers support for Sandvik Coromant Wiper inserts for turning
tools, allowing these productivity enhancing inserts to be used reliably in all aspects of
production machining.
Update stock Edgecam has the ability to keep the stock updated live within the
sequence tree. The stock model is rest material, or material that has not been machined.
Subsequent toolpaths will automatically detect the rest material resulting in 100%
efficiency for any turning toolpath throughout the Edgecam sequence. Update stock is
supported from the most basic 2 axis turning centre, right through to a CYB multi turret
sub spindle Mill / Turn. When back turning into a recess or groove it's important that the
back turning cycle knows the current condition of stock to avoid air cutting and potential
collisions on the approach into the recessed area. On a sub spindle turning centre,
when a component is transferred from the main spindle to the sub spindle, the livestock
transfers with it. Any subsequent machining on the sub spindle will detect the stock in
the state that it left the main spindle which ultimately provides the most efficient
machining sequence possible.
Collision Detection / Simulation - It is imperative that not just the tool in contact with
material is checked for collisions, but also tools that are not in use on a turret. Most
turning centres offer a relatively small working envelope that can be collision rich. A
good example of this is on static turrets where tools such as boring bars, can extend out
further than the tool in cut. Edgecam will not only collision check the tool in cut but also
all of the tools on the turret against the machine tool kinematics, fully supporting Mini
Turrets, capto tooling and programmable steadies.
Swarf Clearance - When machining inside a bore, loose material can build up around
the insert which can result either result in insert failure or severely decreased tool life.
Edgecam will allow you to retract tool out of a bore or away from a diameter after a set
numbers of cuts. The user can retract the tool mid cycle, to a known position, after a set
number of cuts to clear any loose material out of the bore.
Sub spindles - Edgecam fully supports turning centres with a sub spindle & twin turret,
including :
- Bar pull
- Bar feed
- Part pick and return
- Running in conjunction with the main spindle
Twin turret support for both single and twin spindle lathes including :
- Balanced turning
- Z lag options improving metal removal
- Mirrored turning
- Turret synchronisation and simulation
Cycle control
Individual Element offsets - - Edgecam's turning cycles offer the ability to specify offsets
to individual turned diameters, bores, grooves, and faces. This function is useful where a
turned component needs some elements to be finished turned, and others to be left a
grinding allowance for subsequent machining or heat treatment.
Most systems on the market today will only allow you to set a constant offset, where
as Edgecam gives the user full control over offsets for each individual element on the
turn feature.
Break Edges - Subcontract machinist do not always have the ability to go back to their
client to ask them to revise the design to include the chamfers or break edges, even
though they have been asked for on the engineering drawing. Edgecam turning cycles
offer the machinist the ability to specify a break edge where a chamfer has not been
included on the model supplied to them by their client.
Down Cutting - This function within the finish turning cycle alternates the cut direction on
the finish turn profile, so the tool is always down cutting, or it never drags up the face.
This give the enhanced tool life and achieves a superior surface finish.
Sequential Castellation grooving - Traditional grooving cycles wear the tool on one
side after the initial full width cut. With Sequential Castellation grooving, the tool starts at
one groove edge and moves to the other edge, producing full width cuts.
It then goes back and removes the 'rings' left behind by the first cutting pass. This
ensures that the load on the grooving tool is on the front of the tool, opposed to the
sides. It also ensures even wear on the insert.
Rough Turn Sectioning - To keep the tool push off on a long diameter to a minimum,
Edgecam have developed a section strategy where the user can break the rough turn
cycle into sections. The user sets a Z break distance and the roughing cuts are divided
into short sections.
Rough turn Variable cut Depth - This function is to Prevent notches wearing into the
tool. Cuts are alternately 'ramped' then 'normal'. During the ramped cuts, the cut depth
gradually reduces to zero. The next cut (which will be 'normal' and starts at the same
cut advance) then removes the leftover ramp. If a ramped cut is interrupted by the
profile, it follows the profile until it re-joins its ramped path.
Waveform Turning - Waveform turning is designed for round inserts. The toolpath is similar to the Milling cycle where the insert remains at a constant engagement with the material. The main advantage is that the tool has a constant load allowing for higher feed rates to be used and, particularly if lace method is employed, the wear is more evenly spread around the insert leading to prolonged tool life. Consistent tool loads allow much higher feeds, speeds, and allow full depth of cut permitting material removal at the tool manufacturer's recommendations which reduces the machining time.
