EdgeCAM Machine Simulation

EdgeCAM Simulator offers full simulation of the machine tool and machining process for lathes and milling

machines. This enables you to visualize the interaction between the various elements of the machine tool

helping to avoid expensive collisions, optimise the cutting process and reduce cycle time.

Simplified block graphics are created for you by default and their dimensions can be parametrically adjusted

to suit your machine tool configuration.

Optionally, you can substitute the parametric graphics with your own fully detailed graphics by modeling the

machine tool in a solid modeler such as EdgeCAM Part Modeler. Elements of the machine tool such as

heads and turrets are represented as graphics. The 'Machine tree' provides an easy-to-use method of

controlling the display and kinematics of each machine tool component. The graphics are positioned in an

axis configuration built into the Machine Tree (such as upper ATC on the B Axis, B Axis on the Y Axis and

so on, or Table on the C Axis, C Axis on the A Axis and so on).

There are also graphics for fixtures, such as tool mounting blocks, and chucks, that you can store in a

library for use in the machine tool simulation.

The Machine Simulation setup is contained in the code generator; as created in Code Wizard. For correct

simulation you need to specify details such as the axis configuration and the Home positions; see the Code

Wizard help for full details.

EdgeCAM Simulator only checks for collisions between Chucks, Holders (excluding index turret mounting

blocks) & Tools.

Please note that EdgeCAM Simulator is not strictly time-based, so twin turret turning simulations may lose

synchronisation. You can counter this; see Simulator help for details.

Using Machine Simulation - Turning

EdgeCAM Simulator offers full simulation of the machine tool and machining process for lathes and milling

machines. This enables you to visualize the interaction between the various elements of the machine tool

helping to avoid expensive collisions, optimise the cutting process and reduce cycle time.

Here are the key stages in using Machine Tool Simulation:

Create part geometry as normal, in Design Mode.

Switch to Manufacture Mode, which initiates creating a machining sequence. In the Machining

Sequence dialog select an appropriate code generator (that is a code generator that has been set up

for machine simulation in Code Wizard, which is only possible for certain code generator types).

Still In the Machining Sequence dialog, position the machine tool graphical representation.

See more details...

Show or hide the machine tool graphics (Base, ATC and so on) as desired. (We recommend you hide

the graphics after positioning the machine, for an unobstructed view of the part. You would next show

the graphics at the simulation stage.)

See more details...

If required, change the chuck parameters; change the Inner Jaw diameter to so that the jaws appear

clamped around your part for example.

Simplified block graphics are created for you by default and their dimensions can be parametrically adjusted

to suit your machine tool configuration.

Alternatively mount a different chuck.

Optionally, you can substitute the parametric graphics with your own fully detailed graphics by modeling the

machine tool in a solid modeler such as EdgeCAM Part Modeler. Elements of the machine tool such as

heads and turrets are represented as graphics. The 'Machine tree' provides an easy-to-use method of

controlling the display and kinematics of each machine tool component. The graphics are positioned in an

axis configuration built into the Machine Tree (such as upper ATC on the B Axis, B Axis on the Y Axis and

so on, or Table on the C Axis, C Axis on the A Axis and so on).

Set the tool gauge distances. These are crucial as they determine how far the tool projects from its

mounting block, for example on an Index Turret. If no tool gauge distances are specified the tool tip is

positioned exactly at the tool setting position, as set in the code wizard. Therefore if no gauge values

are set the tool is likely to be simulated fully buried in the block.

See more details...

There are also graphics for fixtures, such as tool mounting blocks, and chucks, that you can store in a

library for use in the machine tool simulation.

Optionally set up a job (kit of tools) for an indexing turret. If you have a kit where each tool has been

assigned a position around the turret and appropriate gauge distances set, at any time you can

specify the job in the Machine Sequence dialog to quickly populate the turret with tools.

You can create a toolkit independently from EdgeCAM in Toolkit Assistant.

The Machine Simulation setup is contained in the code generator; as created in Code Wizard. For correct

simulation you need to specify details such as the axis configuration and the Home positions; see the Code

Wizard help for full details.

EdgeCAM Simulator only checks for collisions between Chucks, Holders (excluding index turret mounting

blocks) & Tools.

Alternatively you can set up the turret, and copy the information to a new toolkit, within EdgeCAM.

See how to do this...

Please note that EdgeCAM Simulator is not strictly time-based, so twin turret turning simulations may lose

synchronisation. You can counter this; see Simulator help for details.

See also Adding Machine Simulation to Existing Turning Code Generators.

Machine the part as required.

See more details (on moving the sub-spindle)...

Optionally, simulate in EdgeCAM. This does not show the full machine graphics, as any visible

graphics (apart from the spindles) become hidden. You might need to re-display the graphics as

described in Step 4 above.

Open Simulator and show all the machine graphics; see Step 4 above (the same facilities for

controlling machine tool graphics are shown in EdgeCAM Simulator, as well as in EdgeCAM). Run the

simulation and visually check for collisions.

Before starting to set up and use Machine Tool Simulation, you might want to work through the Machine

Tool Simulation tutorials.

Still In the Machining Sequence dialog, position the machine tool.

See more details...

If your Tool Change position is different to your Tool Home position, you will need to edit this. Click on

M-Functions Machine Parameters to open the 'editing version' of the Machining Sequence

dialog, and edit the settings in Tool Change tab. (Note that the Tool Home tab settings are

unavailable, as this position is set within code generators that support Machine Simulation.)

Show or hide the machine tool graphics (Base, Head, Tables and so on) as desired. (We recommend

you hide the graphics after positioning the machine, for an unobstructed view of the part. You would

next show the machine graphics in Simulator.)

See more details...

Simplified block graphics are created for you by default and their dimensions can be parametrically adjusted

to suit your machine tool configuration.

If required, change the chuck parameters; change the Inner Jaw diameter to so that the jaws appear

clamped around your part for example.

When you come to selecting a tool, in the Loading tab of the toolchange dialog, specify the 'Z Gauge'

distance to determine how far the tool projects from the spindle. (Otherwise tool tip will be positioned

at the tool setting position, as configured into the code generator by Code Wizard, and subsequent

machine simulation will be incorrect.)

Optionally, you can substitute the parametric graphics with your own fully detailed graphics by modeling the

machine tool in a solid modeler such as EdgeCAM Part Modeler. Elements of the machine tool such as

controlling machine tool graphics are shown in EdgeCAM Simulator, as well as in EdgeCAM). Run the

simulation and visually check for collisions.

EdgeCAM Simulator only checks for collisions between Chucks, Holders (excluding index turret mounting

blocks) & Tools.

After performing some machining and simulating it might be apparent that you need to move the part

within the machine, by editing the mating positions.

Please note that EdgeCAM Simulator is not strictly time-based, so twin turret turning simulations may lose

synchronisation. You can counter this; see Simulator help for details.

The changes will cause the machine datum to move, and the sequence will regenerate. The moves to

Tool Change and Tool Home, and the rotary tool paths will be automatically updated.

EdgeCAM Machine Simulation

In both EdgeCAM and Simulator you use the Machine tree in combination with the Properties Window to set

the properties of Machine Tool Simulation graphics.

You can for example set the visibility of graphics representing turrets, chucks and so on. (You can also use

buttons for setting the visibility of the whole machine, or particular graphics types, see more details .)

In EdgeCAM (not Simulator) you can also use the Machine tree in combination with the Fixtures Tree to

mount chucks on a job-by-job basis.

There are also some properties that are shown for information only, such as turret graphic dimensions. To

change these machine properties you need to use Code Wizard, recompiling the code generator - see

Changing the Setup.

Too use the tree:

Make sure the Machine tree and Properties windows are shown.

Then, as necessary to show the branch:

Click to expand a branch and show its contents.

Click to contract a branch and hide its contents.

Simplified block graphics are created for you by default and their dimensions can be parametrically adjusted

to suit your machine tool configuration.
