posted in: News | 0





Release Date: July 15, 2015


BobCAD-CAM has reached yet another milestone with an entirely new Mill Turn module in BobCAD-CAM V28. With revamped mill drilling, the addition of custom tools, tabbing for profiling, and the snap increment for dynamic drawing, this is the most versatile version of BobCAD-CAM yet. Read on to learn more about BobCAD-CAM V28.

CAD Enhancements

Snap Increment for Dynamic Drawing (CAD Module)

Drawing in BobCAD-CAM is now faster and more accurate than ever before. All dynamic drawing functions now have a snap increment, which acts like a uniform grid in the workspace to which wireframe entities or sketch handles are snapped. In addition to the snap increment distance used for most dynamic functions, there is also an snap increment angle available for rotation functions. This creates a whole new level of efficiency for BobCAD-CAM’s dynamic drawing by greatly reducing the number of clicks and data entry modifications. Just set the snap increment and adjust it as needed right from the status bar to create perfectly accurate drawings, the first time, during sketching! You can even quickly turn the snap increment on and off with the shortcut key, Q. All of the previous dynamic drawing functionality is retained and now extended to be more powerful than ever before with the addition of the snap increment. View More

BobCAD-CAM V28 now supports .dxf and .dwg files made with AutoCAD 2016.

Redesigned Mill Hole Drilling, Tapping, and Threading (All Mill and Mill Turn Modules)

Drill Multiple Depths in a Single Feature

All mill hole drilling, tapping, and threading features now use Hole Groups which allow you to define more than one drilling depth within a single machining feature. BobCAD-CAM automatically groups all holes that share the same diameter, top of feature, and feature depth, greatly minimizing the number of features needed to get the job done. Make your drilling features more efficient than ever before, edit faster, and gain greater control of the rapid movements between hole groups using the new Group Retracts. View Example Part and Benefits


The following image shows a basic standard drilling part. In previous versions, this part required at least six features to efficiently drill all the holes in the model (one for each diameter at each of the three levels of the model). Now, thanks to the multiple depths achieved in a single feature using Hole Groups, these holes can be drilled using only two features.

Advanced Retract Options

The new Group Retracts provide advanced options for defining the rapid movement between hole groups. You can now create planar, cylindrical, or spherical retract areas for all types of drilling scenarios. You can even create the rapid movement to follow the tool orientation or the shortest distance to keep your toolpath clean and efficient. View Advanced Retract Toolpath Examples

Drilling Types

All mill hole drilling features are now one of three types: Standard, Multiaxis, or Cross Drill.


Standard Drilling

The default drilling type, standard drilling, handles 2.5 axis drilling for 3-axis machines, including face drilling for Mill Turn machines. View Standard Drilling Toolpath Examples


Mill Standard Drilling Mill Turn Standard Drilling

Multiaxis Drilling

Multiaxis drilling is a completely new drilling type for Mill and Mill Turn jobs that handles all drilling for 4 or 5-axis machines with up to 5-axis positioning. This allows you to drill holes of the same diameter in any orientation within a single feature, eliminating the need to create index systems for each orientation. View Multiaxis Drilling Toolpath Examples

Cross Drilling

Cross drilling is a completely new drilling type that handles radial drilling for Mill or Mill Turn jobs. The software filters your geometry selections so you can easily recognize what holes can be drilled on a mill turn machine that does not have Y-axis capabilities. View Cross Drilling Toolpath Example


Mill Turn Cross Drilling


Hole Geometry Selection Manager

The new selection manager for all mill hole features makes it easy to define the drilling type and manage geometry selections. Calculation options are also provided to determine how the toolpath is calculated for different geometry types, allowing you to be more efficient in all selection scenarios. View Hole Geometry Selection Manager


Drill_Manager_Standard.png Drill_Manager_Multiaxis.png Drill_Manager_Cross.png



Smart Filtering of Geometry Selections

BobCAD-CAM automatically filters the geometry that you select in one of two ways. First, any duplicates that would result in drilling a hole twice are automatically removed. Second, BobCAD-CAM automatically filters your geometry selections based on the drilling type. When you confirm the selection, all holes that do not have the proper orientation for the selected drilling type are removed.


Use Cylindrical Surfaces to Automatically Set Drilling Parameters

When you select cylindrical surfaces, the software automatically sets the diameter, top of feature, and feature depth values for you. Select cylindrical surfaces to speed up your Mill Hole feature creation. View Cylindrical Surface Selection



Mill Enhancements

Custom Tool Shapes for Milling Tools (All Mill Modules)

When creating milling tools, you can now assign geometry to define custom shaped tooling or form tools. You can even define the cutting and non-cutting portions making it easy to create tools that have more than one cutting area. Just create half of the profile to revolve, assign it to the tool, and get accurate program simulation for all your custom tooling. View Custom Tool Example


The following images show two examples of custom tools. Just create a chain for half of the tool profile using solid entities to define the cutting portion of the tool (shown in yellow), and use dashed entities to define the non-cutting portion of the tool (shown in grey).

Tabbing for 2 Axis Profiling (Mill Express Module)

The 2 Axis Wizard now contains a Tabs page which allows for manual or automatic tab creation for profiling operations. You can allow the software to calculate evenly spaced tabs using a number or distance, or you can use manual tabs to select the tab locations directly from the chains in the workspace. Powerful tab parameters allow you to define the distance, height, and angle so you create each tab exactly the way you want it. A preview window displays right inside the Mill 2 Axis Wizard so you can easily confirm the proper tab locations. View Tabbing Toolpath and Cut Stock

Linking Added to 2 Axis Advanced Pocket (Mill Express Module)

The 2 Axis Advanced Pocket now contains a links page giving you more control over the linking parameters of the toolpath. Use a direct, S-link, or retract move between passes or groups with separate controls for each. You can even now use the rapid retract for large gaps option to speed up the retract moves when there are large gaps along the cut. View Link Types


Direct S-Link Retract

Perpendicular Stepover for Advanced Planar (Mill 3 Axis Pro Module)

The Advanced Planar operation is further optimized with a new solution for inconsistent finishing in steep areas. The perpendicular stepover option automatically switches the toolpath direction based on a threshold value to create an improved surface finish in steep areas. Program faster with this more efficient toolpath to get a better result and reduce cycle times. View Perpendicular Stepover Example

Side and Bottom Allowance (Mill 3 Axis Pro Module)

You can now specify the finishing allowance separately for the side (XY) and bottom (Z) in the 3 Axis Pro toolpath strategies. This gives you more control over the roughing toolpath, so you can minimize or even eliminate the semi-finishing process for your 3-axis operations. View Side and Bottom Allowance Example


The following images show the deviation analysis of a 3-axis part that is roughed using a different allowance for the bottom and sides of the part. The bottom of the part has a smaller allowance and the sides of the part are given a larger allowance. The target part is shown with a sectional view of the cut stock to better show the difference.

Wrapped Toolpath Improvements (Mill 4 Axis Standard Module)

The Wrapping Group for 4-axis wrapped toolpaths now allows for the selection of wrapped geometry. Eliminate the need to unwrap the geometry first, just select it right from the solid model. You can also now use the current stock to set the wrapping diameter. New unwrap controls provide a tolerance value and an arc fit option for the background calculations. You can even select whether to show the toolpath as wrapped or flat, giving you a more accurate representation of wrapped toolpaths. View Wrapped Toolpath Example

Revolve Stock Type (All Mill Modules)

The Stock Wizard has been upgraded with a completely new stock creation method: Revolve. The revolve stock type, previously only available for lathe jobs, was added to all CAM Jobs to allow you to define stock geometry by revolving a wireframe chain. While helpful for any job type, the revolve stock type was an essential addition for our new Mill Turn module. View Revolved Stock Example

Mill Turn Module

BobCAD-CAM V28 marks the release of another brand new module for mill-turn machining. Mill Turn may also be called turn milling or multitasking, and it is the same as a lathe equipped with live tooling (a turret that can drive milling tools). Support is provided for all types of mill turn machines, including machines with Y-axis capabilities as well as multiaxis machines that include a milling spindle. BobCAD-CAM can create programs for most available mill-turn machine configurations from single spindle/single turret to multiple spindle/multiple turret machines.

Mill Turn Jobs

The Machining Job dialog box now includes the Mill Turn job. Just select the machine and go directly to the Stock Wizard to assign a workpiece, create stock, and then complete the Machine Setup to define the machining origin, work offset, and clearance parameters for the job. When you finish, the Mill Turn job is added to the CAM Tree with everything you need to start creating the program. View the Machining Job Dialog Box and Mill Turn Job in the CAM Tree

Mill Turn Machine Definition and Submachines

The machine definition now supports the creation of mill-turn machines so you can define a realistic virtual representation of your machines in BobCAD-CAM. Set up your machine parameters and limits to create the proper posting output, and define the geometry for the machine to get an accurate simulation of your programs. Setup wizards are provided to help guide you through creating turrets and/or milling spindles for mill turn machines. View Mill Turn Machine Definition and Virtual Machine Examples

Adapter Library

The Adapter Library was added so you can define the tool holding equipment for mounting your lathe or mill tools to the machine turret and define the tool mounting locations on the adapter. The Tool Adapter Definition includes a preview window for visual confirmation of the proper settings. You can assign custom geometry to make your program simulation as accurate as possible. You can also organize your adapters to your preferences using custom categories. View More

Mill Turn Tool Crib

A completely new tool crib was created to help you manage all of the adapter and tool mounting for mill turn jobs. You can easily add tools or tool adapters from the system libraries, and then mount them to the appropriate machine device. The Mill Turn Tool Crib even includes a preview window to display the machine device, tool adapters, and tools to help you visually confirm the proper setup. Just like the Mill and Lathe Tool Cribs, you can even save and load your tool crib to eliminate the need to repeatedly define the same information. Define the tool crib once with your most common or repeatable setup, save it, and then load it to use as a template and speed up your mill turn program creation. View the Mill Turn Tool Crib



Machine Simulation Pro

Our extremely powerful machine simulation now includes support for all types of mill-turn machines. With the tight working envelope of many mill turn machines, the pro simulation allows you to test and confirm your programs before running them on the physical machine, providing you with peace of mind. View Pro Simulation Virtual Machine




The Mill Turn job also supports MDI, or manual data input, which allows you to manually define machine movement as needed for your mill-turn machining operations. MDI allows you to build lines of code by adding commands to move the various machine components as needed, for example, for handling part transfers, parts catchers, or tailstock devices. MDI is available for all operations in Mill Turn jobs. View the MDI Page




Cutter Compensation for Mill Turn Simulation

IMPORTANT:     There is a known issue when using machine cutter compensation in Mill Turn simulation. For this release when using machine cutter compensation, the toolpath is simulated without the compensation. In order to create an accurate simulation, please use System Compensation. The posted code for Machine Compensation is not affected and will work accurately.

General CAM Enhancements

Workpiece Selection for Simulation (Mill, Lathe, Mill Turn, and Wire EDM)

You can now assign workpiece geometry (the target part), to determine exactly what geometry displays in the program simulation window, regardless of how much geometry is visible in the workspace. You can assign workpiece geometry during the job setup or using the Workpiece in the CAM Tree. Streamline your simulation and simplify the process of comparing the cut stock to the workpiece for files with more than one model. View More
