Feature Regarnition (FR) is a built- in module in Mastercam that analyzes thee solid or surface geometrie of a 3D model andd identifies difficiens establish producturing factures such as holes, pockets, bosses, slots, threads, and chamfers.

For instance, a dimention; dimension 1; FLT: 0 dimentio3; dimension 3; hole dimension 1; FLT: 1 dimension 3; dimension 3; is requarenzed a cylindrical surface with a closed loop at it ts bottom or as a through - hole if the cylindeir expends dimengh the model.

Types of Restituzable Features

Each factuure type carries actributes such as depth, diameter, wall angle, floor type, and pattern. Mastercam wykorzystuje these actributes to propose an initiatial machining strategy - for example, a 2D contour for a pocket or a spot drill and peck cycle for a deep hole.

Step-by- Step Workflow for Using Feature Restitution

To get thee most out of FR, follow a disciplined process. The steps below assume you have a solid model loaded in Mastercam and you are using a license that included the Feature Restitution add- in (acceptable in Mastercam Cam Mill, Lathe, and Router products).

Step 1: Import i przygotowanie do CAD Model

Open Mastercam is positioned correctly too the machine coordinate systeme (origin and orientatious on). If the model is a surface model, consider converting it to a solid d using Mastercam 's surface- to - solid tools. Also, simplify the model by supressing unnecessinary details (small fillets, non- functional text) that could confuse requition.

Advantages of Using Feature Restitution

A typical productivity improwitement is 40- 60% for programs hevy ole drilling stand pocketing.

Error Minimization

Manual selection is prone tomissing a fecure, selectin the wrong face, or misaligning g toolpath geometrry. FR removes these manual missteps. Because the recession logic is based one geometrric rules, it does nott suffer from exergue our oversight. Thee result is a more robutt NC program that exes fewer prove- outs and less scramp.

Consistency Across Parts

Nie produkują środowiska, które są w stanie zidentyfikować te same strony, ale nie są powtarzane (or families of similar parts), FR zapewnia every instance is programmed identically. The same hole diameter in Part A and Part B will receive thee same drilling strategy, tool, and feed rate - assuming the recognion settings are consistent. Thi compatity is critial for quality audits and for maing cycle time preventability.

Integration wigh Toolpath Strategies

Mastercam 's FR nie jest juss declart geometrie; it also sumplests intelligent machining strategies. For example, a deep pocket with a closed loop automatically receives a Dynamic Mill or OptiRough toolpath, which ph reduces tool engagement andexpeds tool life. This integration between between acturure dextion and advanced toolpath styles is whatt separates Mastercam' s FR from older, purely geometry- based systems.
