Machining

ABS

ABS, a ter-polymer is processed by polymerization on styrene and acrylonitrile. This process is carried out in the presence of polybutadiene. Therefore, by varying the proportions of polybutadiene the properties such as impact resistance, toughness and heat resistance can be controlled.

ABS Design Guidelines for Machining

ABS material properties - wall thickness

Wall thickness

  • Minimum wall thickness should be 1.5mm anywhere.
  • For better results, it is recommended to maintain wall thickness above 2mm.
ABS material properties - minimum details size

Minimum detail size

  • Minimum diameter that can be processed is 1mm.
  • Metal inserts may be required for softer materials.

ABS material properties - support

Design consideration

  • Undercuts, T-slots, Dovetail slots are difficult to process.
ABS material properties - emboss

Text impressions

  • Engraving is easier than embossing.
  • Embossing requires more material removal.
  • There are thickness limitations associated with embossing.
ABS material properties - emboss

Corner Radius

  • Corner radius depend on the tool diameter
  • Too small diameters are hard to machine
  • Corner radii, if any, must be limited to 1mm diameter
