Fixture Design with FIXES: the Automatic Selection of Positioning, Clamping and Support Features for Prismatic Parts

FIXES is a computer aided system for the automatic generation of set-ups and for fixture design for prismatic parts, to be used in an integrated process planning environment. The generation of set-ups having been described in a previous paper [9], this paper concentrates on fixture design, in particular the automatic selection of the faces for the positioning, clamping and support of workpieces. The selection procedures described are based on both the topology of the prismatic part and the geometric relations between the different part elements (features). The geometric relations are evaluated with the aid of a so-called Converted Tolerance Scheme

FIXES, a system for automatic selection of set-ups and design of fixtures

This paper reports on the development of a computer aided planning system for the selection of set-ups and the design of fixtures in part manufacturing. First, the bottlenecks in the present planning methods are indicated. A brief description is given of the CAPP environment PART, in which FIXES is incorporated. The planning procedure of FIXES consists of two parts: the selection of set-ups and the design of a fixture for each set-up. The automatic selection of set-ups is based on the comparison of the tolerances of the relations between the different shape elements of the part. A tolerance factor has been developed to be able to compare the different tolerances. The system automatically selects the positioning faces and supports the selection of tools for positioning, clamping and supporting the part. A prototype implementation of FIXES is discussed

Adaptive Municipal e-forms

Adaptation of electronic forms seems to be a step forward to reduce the burden for people who fill in forms. Municipalities more and more offer eforms online that can be used to request a municipal product or service. To create adaptive e-forms that satisfy the need of end-users, involvement of those users in design activities and evaluation is necessary. This paper describes the design of adaptive municipal e-forms and the way user-groups were involved in the design activities and will be involved in evaluation

A Narrative Inquiry into the Experiences of Teaching Artists in Community-Based Practice

This research inquired into the experience of identity making of teaching artists over time and in relation to a community-based practice. The methodology was a narrative inquiry. Experiences of belonging and agency as they relate to identity making were explored. Three teaching artists working in community-based practices were interviewed in a non structured conversational format, which consisted of four meetings with each participant occurring over a period of several months. Temporality, place, and social context were considered throughout the research. Belonging was explored in relation to such experiences as validation, coherence, and negotiating between different communities of practice. Agency was explored in relation to meaning making, imagination, the challenges of the creative process, and the landscape of the art studio. The element of freedom in the community-based teaching practice of the participants was considered with the experience of vulnerability that ran alongside. Encouraging others through care in teaching was found to be a significant experience for the participants. The shaping of their agency in teaching was supported by a sense of belonging. Seeking a greater sense of belonging was in and of itself an agentic act by the participants. Experiences of belonging and agency were linked to and supported by the participants’ artist practice
