investing in CAM software guide

  1. 1. Investing in CAM software GUIDE TO
  2. 2. A Guide to investing in CAM software <ul><li>Why invest in CAM? </li></ul><ul><li>Answer : You could get - </li></ul><ul><li>Faster and more reliable CNC programming </li></ul><ul><li>Easier or automated programming </li></ul><ul><li>Better CAD system compatibility </li></ul><ul><li>More efficient machining processes </li></ul><ul><li>Higher quality parts at less cost. </li></ul>
  3. 3. Evaluate your own needs <ul><li>Is your work 2D, 3D or does it require 5 axis CNC machining? </li></ul><ul><li>What types of CNC machines need programming? </li></ul><ul><li>Which CAD systems do you need to communicate with? </li></ul><ul><li>What skills are available within the company? </li></ul>
  4. 4. <ul><ul><li>Evaluate potential suppliers </li></ul></ul><ul><li>Quality of support – delays can stop production. </li></ul><ul><li>Quality of training – shortcuts here are a false economy. </li></ul><ul><li>Quality of cutterpaths – these will significantly effect the cost and quality of the finished part. </li></ul><ul><li>Sufficient development resources – will they keep you at the leading edge of technology? </li></ul><ul><li>Visit existing users to check the supplier’s claims. </li></ul>
  5. 5. Benchmarking – Checking for CAD compatibility <ul><li>Test some real CAD data from your customers in the CAM software. </li></ul><ul><li>Check to see how well designs can be manipulated, repaired and interrogated. </li></ul><ul><li>Hybrid modelling of surfaces and solids makes design manipulation easier. </li></ul><ul><li>If the CAM software can tolerate holes in the surface model, this can save a lot of time. </li></ul>
  6. 6. Benchmarking – Ease of use <ul><li>CNC programming systems which are hard to operate may fall into disuse. </li></ul><ul><li>More people can use an easy or automatic system, increasing productivity. </li></ul><ul><li>Easy software can be used on the shop floor making the most of operator’s skills. </li></ul><ul><li>Automatic CNC programming makes it difficult to make a mistake and produces consistent high quality results. </li></ul><ul><li>Easy systems are quick and intuitive providing a fast return on investment. </li></ul>
  7. 7. Benchmarking – Speed of calculation <ul><li>Complex tasks can take a long time to calculate. </li></ul><ul><li>Does the software support the latest multi-threaded processing? </li></ul><ul><li>Can the CAM software allow batch processing of calculations overnight? </li></ul><ul><li>Does the licensing allow programming to continue when calculations have started? </li></ul><ul><li>Can changes be made to the program without recalculation? </li></ul>
  8. 8. Benchmarking – Capacity for expansion <ul><li>Is the CAM software capable of meeting future requirements? </li></ul><ul><li>Floating licences can allow many more users to access the software – useful for shop floor programming. </li></ul><ul><li>Are there additional modules for 5 axis CNC machining or feature recognition, for example? </li></ul><ul><li>Is there extra software for applications such as manufacturing software or a CAD viewer ? </li></ul>www.sescoi;com
  9. 9. Benchmarking – Quality of cutterpaths <ul><li>Reliable, accurate and safe toolpaths and CNC code are an essential element of any CNC software. </li></ul><ul><li>Check the quality of the postprocessed data generated for your machines. </li></ul><ul><li>Watch out for air cutting or excessive retract moves. </li></ul><ul><li>Are toolpaths smooth? This is especially important for high-speed machining. </li></ul><ul><li>Does the CAM software know where excess material is located, and does it use stock or rest models? </li></ul>
  10. 10. Benchmarking – Quality of cutterpaths - continued <ul><li>Check to see if toolpaths have been duplicated in subsequent operations. </li></ul><ul><li>Is it easy to graphically edit toolpaths? </li></ul><ul><li>Look for constant tool loads. This will improve both part quality and tool life. </li></ul><ul><li>Does the software avoid sudden changes in the direction of the tool? </li></ul><ul><li>Does the software use climb milling where possible? </li></ul><ul><li>Are the material entry and exit strategies smooth? </li></ul>
  11. 11. Benchmarking – 5 axis CNC machining <ul><li>Is it possible to automatically generate a 5 axis toolpath? </li></ul><ul><li>Are there standard 5 axis CNC toolpaths such as rolling, normal to surface and profiling? </li></ul><ul><li>Dedicated toolpaths for parts such as blades or impellers are useful for specialist applications. </li></ul><ul><li>Can the CNC software cope with undercuts? </li></ul><ul><li>The software should consider the angular limitations of the machine tool as well as the tool length. </li></ul>
  12. 12. Benchmarking – Simulation and collision avoidance <ul><li>Check that the CAM software considers the kinematics of the machine tool. </li></ul><ul><li>If rotary axis limits are reached does the software automatically unwind or flip the axis? </li></ul><ul><li>Can the CNC software suggest a tool length to reach deep parts of the job? </li></ul><ul><li>The ability to compare the simulation with the original model will ensure that the part has been completely machined . </li></ul>
