Tech Tuesday: Advanced Roughing
Posted by Al DePoalo on 13 July 2021 09:10 AM

Tech Tuesday is a weekly blog that addresses some of the most common questions and concerns that I hear throughout the previous week from users of BobCAD’s CNC software. Both customers and future customers are more than welcome to leave a comment on what they would like to see covered for the following Tech Tuesday.

 

CAD CAM Software Make CNC Programming Easier

Shops of all sizes are pushed to setup jobs faster, rough stock quicker, and do it in less time.
 
How can CNC Software help you reduce setup times, and program faster? Keep reading this week’s Tech Tuesdays to learn about features you can start using today for faster tomorrow.
 

CAM Tree Templates

Save your CAM Tree for future jobs
 

CAM Tree Template

 
CAM Tree Templates allows users to save a previous job’s CAM Tree and use on future projects. Huge time saver for those shops that standardize their workflow. Capture and reuse settings like, stock setup, zero position, tools, Machining Features, operations, and settings is made easy with CAM Tree Templates.
 

Optimize Your Setup

Change Jobs Faster
 
Where possible, using a standard setup reduces time. There is no one size fits all, but where you can standardize working holding, you’ll get an instant productivity boost.
 

Change Jobs Faster

 
Subplate fixtures, zero point work holding, modular work holding systems and other quick change setups provide the much needed flexibility that helps to get parts out the door faster! Reduce the guesswork and standardize your setup.
 
A standardized setup could be as simple as always establishing a standard work offset location, to the type of jaws you use. Creating consistency in your process is the goal to achieve streamline workflows.
 

Probing

Automate for efficiency
 

Probing Automate for efficiency

 
One of the most popular options for new cnc machines purchases is a probe setup. Automating touching off tools, picking up your work offset, adjusting tool offsets, and inspecting parts are some of the power play moves cnc probing brings to the table. If your machine has a probe, use it, if it doesn’t get one and use it! CAM software makes programming cnc probes easier, the same way it makes creating g-code easier. Speed things up by using your geometry to drive probing cycles.
 

Advanced Roughing

Your go to roughing strategy for 3D models
 

Advanced Roughing go to roughing strategy for 3D models

 
What makes Advanced roughing such a powerful toolpath operation? Not all toolpaths are created equal, nor do they all recognize stock. Many of BobCAD Mill Professional toolpath operations are stock aware, which is a huge benefit, especially when roughing. Using the defined stock geometry and the selected workpiece, users can speed up part programming by automatically targeting where the material is.
 
Want to eliminate toolpath that requires plunge moves?
 
Entry
 
BobCAD’s Advanced Roughing operation has toolpath features that simply make programming easier. Using the leads entry settings users can uncheck center cutting tool. This option will eliminate toolpath created in locations that requires the tool to plunge into stock requiring a center cutting tool.
 

Advanced Roughing operation has toolpath features that simply make programming easier

 
Automatic toolpaths like Advanced Roughing streamlines workflows by reducing geometry perpetration typically needed to target stock, like creating boundaries or “capping surfaces” to avoid tools plunging into part features.
 

Target Flatlands

 
If you model has multiple level “shoulders” how can you ensure they are targeted during the roughing process?
 
Machine Flatlands
 
With this option turned on, additional toolpath will be created on the flat areas of your parts.

High Speed Machining

Increase throughput with faster cutting feeds.
 
This widely adopted toolpath technology is designed to speed up tool motion, one way it accomplish this is by trochoidal toolpath motion (smooth toolpath transitions) controlling tool engagement. How else can CAM software help speed things up.
 
Adaptive Clearance
 
Use the links adaptive clearance settings to reduce or eliminate tool up /down retracts for reposition Using the retrack threshold you can force the tool to reposition while keeping the tool down, verse having a clearance move.
 

Fixture Selection and Avoidance

Avoid fixtures without using boundaries.
 
Holding your stock and avoiding clamps / fixtures is made a much easier process when using advanced allowance.
 
Allowance
 
Using advanced allowance, you can select part features you want to leave custom amounts on stock on, or avoid all together. Part geometry selection is used to leave additional stock, and Fixture geometry selection is used to avoid. Use the check box for use setup fixture to avoid your CAM Tree selected fixture.
